o PiecewiseInterpolation, RooProdPdf, RooRealSumPdf, RooProduct, RooAddPdf,
RooAddition, RooHistPdf, RooHistFunc
- Implement isBinnedDistribution
o RooSimSplitGenContext
- New implementation of RooAbsGenContext for simultaneous pdf.
The difference with the existing RooSimGenContext is that
the logic is implemented at the generate() level rather than
the generateEvent() level, which allows to perform mixed
binned/unnbinned generation
o RooBinnedGenContext
- New implementation of RooAbsGenContext that performs binned
generation, with an unbinned weighted dataset as output.
This new context implements the algorithm of
the now deprecated method RooAbsPdf::generatedWeightedUnbinned()
o RooSimultaneous
- Implement method autoGenContext() that selects a split context
can case (partially) binned generation is requested
- Deprecate generateMixed() - now absorbed in generate()
o RooAbsGenContext
- Make generate() virtual
- Implement processing of extend mode here too
o RooCompositeDataStore
- Fix compiler shadowing warnings
o RooAbsPdf
- Add method binnedGenContext() to return a generator context
for binned generation
- Add method autoGenContex() that can return either a binned
or unbinned context depending on the input and circumstances
- Add support for ExpectedData(),GenBinned(),AllBinned() and AutoBinned()
in generate()
- Deprecate generateWeightedUnbinned() - now absorbed in generate()
o RooLinkedList, RooLinkedListElem
- Adjust memory management of chain elements to avoid slow heap growth

argument constructor each time
o RooTrace
- Add (dummy) method callgrind_zero() and callgrind_dump() as hook functions
to facilitate improved callgrind profiling
o RooAbsCategory

and lookup associated string label on the fly, whenever it is requested
o RooFormular
- Eliminate overloaded getVal() as its functionality is now provided in
RooAbsReal::getVal()
o RooAbsOptTestStatistic
- Implement new fast-attach mechanisms for pdf and datasets: only readjust the

the pdf to the dataset observables. This results in a _much_ faster
operation of setData() and no longer entangles the test statistics with observables
of datasets that may be deleted during the lifetime of the test statistic
o RooSimultaneous
- Overload fillDataHist() with new version with correct normalization (from Scott Snyder)
o RooCategory
- Adjust getLabel() so that it retries labels associated with the current index on the fly
o RooCatType

o RooAbsCache
- New abstract base class for cache objects associated with RooAbsArgs.
Caches register themselves with the owning RooAbsArg and propagate
all necessary state changes and meta information to objects in the cache
o RooCacheManager
- Concrete template implementation of RooAbsCache with an interface
and functionality styled after RooNormListManager. The template class
provide no special handling for cache contents that includes RooAbsArg
objects and does not forward hook calls. It is thus mostly intended
to cache basic types indexed on a normalization/integration configuration
o RooObjCacheManager
- Class derived from RooCacheManager<RooAbsCacheElement> that implements
all proper call forwarding and handling of state and other meta information
to RooAbsArg objects embedded in the cache elements. To facilitate this
functionality the RooAbsCacheElement defines a pure virtual method
containedArgs() that must be implemented to expose its contents to
the cache manager. The default behavior on a serverRedirect hook is
to sterilize the cache. OperMode changes are not forwarded by default
to the cache contents as cached objects do not necessarily have the
same operation mode (e.g. if the cache contains an integral of its owner).
Any calls to optimizeCacheMode(), printCompactTreeHook(), and findConstantNodes()
are forwarded. Moreover, optimizeCacheMode() calls are remembered and
any objects inserted in the cache after such a call was received will be
optimized upon insertion in the cache
o RooAbsCacheElement
- Abstract base class for objects to be managed by RooObjCacheManager. Each
object must in addition to its payload implement the containedArgs()
member function that exposes the RooAbsArg object content to the manager
for processing. The argument passed to containedArgs() indicates the use
case for the returned list of objects, allowing the cache payload to
return different lists depending upon use. This is for most applications
not required.
o RooAbsCachedPdf
- Abstract base class derived from RooAbsPdf for p.d.f.s that implement
value caching in a grid over the entire domain of the observables.
The base class implements the overall caching logistics and manages
the RooDataHists and RooHistPdfs that respresent the cached contents.
Derived classes must inputBaseName() defined a unique name prefix for
all cache objects, actualObservales() and actualParameters() to
determined the actual observables and parameters given a set of
available observables and fillCacheObject() which should fill the
RooDataHist cache for a given obs/params configuration with the
p.d.fs values.
o RooAbsSelfCachedPdf
- Abstract base class derived from RooAbsCachedPdf that implements
all of the required logistics in RooCachedPdf and only require
derived classes from RooAbsSelfCachedPdf to implement evaluate().
Any class derived from RooAbsPdf can thus be trivially switched
to derived from RooAbsSelfCachedPdf and gain the caching functionality.
o RooCachedPdf
- Concrete class derived from RooAbsCachedPdf that implements
the caching of an externally provided p.d.f in the constructor.
o RooFFTConvPdf
- Concrete class derived from RooAbsCachedPdf that implement generic
numeric convolution of two input p.d.f.s using FFT technique
and convolution theorem. Actual FFTs are calculated by FFTW
through TVirtualFFT interface in ROOT. Present implementation only supports
convolution in one dimension, but this will be extended later
as there are no fundamental limitations in RooAbsCachedPdf nor FFTW.
o RooHistPdf
- Moved from RooFit to RooFitCore because it is used by caching classes
o RooProdPdf
- Use new RooObjCacheManager to store partial objects
- Fix memory leak (already patched in 15.0.14h)
o RooDataHist
- Use new RooCacheManager template to cache partial bin volumes
- Add new set(),setAllWeights() method to update current weight and all weights
respectively, for use in cached p.d.f.s
- Add sliceIterator() that iterates over all bins in a lower dimensional
slice of the dataset
o RooDataHistSliceIter
- Class derived from TIterator that implements the iteration
over a slice in a reduced number of dimensions in a RooDataHist
o RooMsgService
- Speed up processing of debug streams in cases where no debug streams are active
- add macros series oocoutX and oocxcoutX that allow to associate message with
a different object than *this
o RooRealBinding
- Interface new setValue method that allows value to be set outside default
domain, but inside given alternate named range. For use in numeric integrator
bindings
o RooAbsRealLValue
- Add new inRange() method with range name specifier to check against chosen
range instead of default range
o RooCmdConfig
- Fix dangling return pointer problem in decodeStringOnTheFly() method
o RooNameSet
- Fix bug in refoll()
o RooChi2Var, RooNLLVar
- Add processing of AddCoefRange() named argument
o RooConvCoefVar
- Hold p.d.f in proxy without value/shape state propagation to obtain
correct dependency of RooConvCoefVar through separate set proxy
with parameters that do have state propagation
- In getAnalyticalIntegral() ask for integration coefficient specific
to coefficient (following interface change in RooAbsAnaConv)
o RooEfficiency
- Follow interface change in RooCategoryProxy
o RooAbsAnaConvPdf
- Use new RooObjCacheManager to hold normalization and coefficient representations
- Extend getCoefAnalyticalIntegral() interface so that each coefficient
can have a separate integration configuration
- Modify makeCoefVars() such that it constructs the RooConvCoefVars with
actual dependents for each coefficients, rather than inserting dependencies
of any of the coefficients in each coefficient. This logic requires support
from the implementation class that is interface through a new member function
coefVars()
o RooAbsReal
- Add Boolean data member treeVar that indicates is value buffer is also
branch buffer of a tree. This information is already present in the RooAbsReal
but is relatively expensive to retrieve and is always needed in the inner
loop of data set operations. This extra member significantly speeds up operations
- Remove superfluous _norm[] token in name returned by integralNameSuffix() if
no normalization set is supplied.
- Add a fillDataHist() method that fills a given RooDataHist with a sampling
of the given function. Added for support of caching p.d.f.s
- Downgrading warning on non-dependent projection variables in plotOn() to
a debug level message
- Remove function optimizeDirty(),doConstOpt(),undoConstOpt(),findCacheableBranches()
findUnusedDatasetVariables() and findRedundantCacheServers() as part of reorganization
of optimization functionality.
o RooAbsCollection
- Use iterator semantics instead of vector semantics to process RooLinkedList
contents in assignment operator
- Add utility function contentsString() returning stl string with names
of contents
o RooAddPdf
- Rewrite cache management using new RooObjCacheManager that holds projection
integrals, range integrals and supplemental normalization lists
o RooAbsOptGoodnessOfFit
- Improve handling of normalization ranges and reference ranges for test statistics
containing RooAddPdfs. New named argument in fitTo() and RooNllVar::ctor() pass
reference range for fractions in RooAddPdf components that do not have an explicit
fixed definition already. Name all normalization ranges explicitly after the
subrange to which the're applied to avoid name clashes and conflicts if multiple
normalization ranges are involved.
- Rewrite informational messages through RooMsgService
- Implement new constOptimizeTestStatistic() function that signals all test statistic
components of a RooAbsArg expression tree to perform their constant term optimization
- Implement new optimizeCaching() driver function that changes default lazy-evaluation-with-caching
scheme to test statistic scheme where only parameters objects propagate state changes and
where all components that depend directly or indirectly on observables have lazy evaluation
disabled. Changes to p.d.f objects are delegated to RooAbsPdf::optimizeCacheMode(). Changes
to dataset are delegated to RooAbsData::optimizeReadingWithCaching()
- Implement new optimizeConstantTerms() function that is back end for constOptimizeTestStatistic
implementation.
o RooAICRegistry, RooNormSetCache
- Remove tracking of allocation cycles of RooArgSets as this scheme is superseded by
memory pool mechanism for RooArgSet allocation
o RooMappedCategory
- Follow interface change in RooCategoryProxy.
o RooRealMPFE
- Follow reorganization of optimization functionality: implement new constOptimizeTestStatistic
function for forwarding to slave processes.
o RooRealVar
- Add new setVal() function with range name to facilite setting of values that are outside
default range, but inside specified alternate range. Needed for numeric integration and
certain RooAddPdf coefficient projection.
o RooAbsArg
- Make state management functions public [is/set][Value/ShapeDirty](), setOperMode90
- Add static _flipAClean boolean to support setACleanAdirty() static method.
- Implement mechanism for registration of cache objects with base class RooAbsCache.
Forward all calls to operModeHook(), redirectServersHook(), optimizeCacheMode()
and printCompactTreeHook() to all caches for further processing
- Define constOptimize() function and provide default implementation that forwards
to all servers
- Implement optimizeCacheMode() function that puts expression tree in optimized
caching for test-statistics operations (only cache/lazy evaluate nodes that
do not (indirectly) depend on observables
- Implement findConstantNodes() function that identifies all nodes that depend
exclusively on constant observables and >0 observables that are eligible
for precalculation and caching in test statistics operations by
RooAbsOptTestStatistic::optimizeConstantTerms()
- Define constOptimizeTestStatistics that signal an expression tree that any
embedded test statistic objects should perform their constant term optimization.
Default implementation in RooAbsArg forwards call to all servers.
o RooAbsPdf
- Use new RooObjCacheManager to manage normalization integrals cache.
- Process new SumCoefRange() option in fitTo() that sets the coeffient
interpretation range for all embedded RooAddPdf objects of which
the interpretation range was not explicitly set
- Extend interface of fixAddCoefNormalizationSet(): add extra argument
that controls if AddCoef normalization set are forcibly overruled
for objects that already have an explicit range setting.
o RooRealIntegral
- Add some informational messaging through RooMsgService, rewrite existing ones
- Speed up numeric summations by precreating the involved RooSuperCategory
in the ctor rather than in evaluate().
- Fix bug in dependency insertion: explicitly require servers to be value
server to avoid pulling in fake dependents.
- Remove obsolete data members
- Implement new setACleanADirty() function that atomically flips state of
all AClean objects to ADirty for the duration of the integration step.
Replaces the much more expensive prepareACleanFunc() that did this
only for the objects involved.
- Process factorizing terms in integral only if the list is not empty
- Process Jacobian terms in integral only if the list is not empty
o RooAddGenContext
- Adapt to cache management chanches in RooAddPdf
o RooNumIntFactory
- Use STL classes for internal memory management
o RooSetProxyy
- Implement operator new() and operator() delete as required because
RooArgSet implements them
o RooAbsGoodnessOfFit
- Store and forward AddCoefRange information for embedded RooAddPdf objects
- Implement constOptimizeTestStatistic() and forward to components
o RooErrorVar
- Follow inRange() interface change in RooAbsRealLValue
o RooConvGenContext
- Adapt code to make it work with both RooAbsAnaConv objects and
the newly introduced RooFFTConvPdf
o RooMinuit
- Follow reorganization of optimization functionality
o RooProjectedPdf
- Store projection using new RooObjCacheManager
o RooGlobalFunc
- Add RooFit::SumCoefRange() named argument for RooAbsPdf::fitTo()
and RooNLLVar::ctor() and RooChi2Var::ctor()
o RooClassFactory
- Extend existing makePdf(),makeFunction and makeClass() functions
to also accept RooAbsCategory arguments, to accept an optional string
inserted as the return value expression inserted in the
evaluate() method of the class created, as well as as option string
specifying one or more analytical integrations of the given function
expression that will be advertised in the generated getAnalyticalIntegral()
code and implemented in the generated analyticalIntegral() code
- Add makeAndCompileFunction() and makeAndCompilePdf methods that
generate the code and immediate compile it through ROOTs ACliC interface.
These functions have a simpler interface because the list of arguments
of the function to be created can be specified as a const RooArgSet&
rather than a string with a list of names, thus making it easier
for on-the-fly definition of compiled objects.
- Add defineFunction() and definePdf() methods define and compile
a function/pdf using the above functions and immediately instantiate
an object of the given type passing the specified RooArgSet arguments
to the constructor of the object. These functions make a compiled
equivalent of RooFormulaVar based on the TFormula interpreter, i.e.
RooAbsReal* f = new RooFormulaVar("f","D(1-2w)",RooArgSet(D,w)) ;
becomes
RooAbsReal* f = RooClassFactory::defineFunction("f","D(1-2w)",RooArgSet(D,w)) ;
o RooAbsCategory
- Add Boolean data member treeVar that indicates is value buffer is also
branch buffer of a tree. This information is already present in the RooAbsReal
but is relatively expensive to retrieve and is always needed in the inner
loop of data set operations. This extra member significantly speeds up operations
- Construct explit clean name for TBranch name if node is cached, equivalent
to what is done in RooAbsReal. Needed because new constOptimizer can also
cache RooAbsCategory objects
o RooArgSet
- Implement operator new() and operator delete() to implement memory pool scheme
for RooArgSets. The goal of this implementation is to insure that two RooArgSet
pointers are _never_ the same. This allows to RooNormSet cache manager to safely
and quickly index integration and normalization configurations by evaluating
the contents of a RooArgSet only the first time it sees it.
o RooSimultaneous
- Implement caching of partial integrals using new RooObjCacheManager
- Following interface change in RooCategoryProxy ;
o RooAbsData
- Defined pure virtual methods optimizeReadingWithCache() and allClientsCached()
o RooTreeData
- Implement optimizeReadingWithCache() which determines given a p.d.f to be
evaluated and a list of the nodes that are cached for it, which observables
in the dataset are no longer required because they are either not an observable
of the p.d.f, or they exclusively feed nodes that are cached. Reading of these
observables is disabled through SetBranchStatus().
- Move allClientsCached() utility function here from RooAbsReal.
o RooCategoryProxy
- Remove const char*() conversion operator in favor of a const char* label() method
to remove possibly ambiguities in C++ math expressions involving category proxies.
o LinkDef3.h
- Add newly defined classes

Preparation for V1.04 -- RooProdPdf maintance and upgrade
---------------------------------------------------------
o LICENSE, RooBanner
- Update to year 2004
o RooAbsArg
- Add DeleteWatch debug feature: verbal notification
if an object with this flag is beign deleted
o RooAbsGenContext, RooGenContext, RooAddGenContext,
RooConvGenContext, RooSimGenContext, RooMCStudy
- Introduce concept of auxiliary proto variables, which are
generated by other PDF components rather than an external dataset
o RooAbsPdf,RooConvolutedPdf,RooSimultaneous,RooAddPdf
- Modify genContext() to allow optional specification of auxiliary
proto variables
o RooCmdArg
- Add RooProdPdf as friend
o RooGenProdProj
- Modify so that it will work without a denominator term as well
- Fix in memory management that created hidden links between deep
cloned trees that involved RooProdPdf nodes with cached information
o RooProdGenContext
- Enhance functionality so that it can correctly and optimally
generate events for 'correlated product' PDFS. Now, irriducible
PDF terms are generated in a dependency order: 'imported
dependents', i.e. dependents over which a PDF doesn't normalize
are always guaranteed to have been generated by another term
before the importing term is generated. Left over terms wich are
cross importing cannot be disentangled with a linear dependency
scheme and are generated as a monolithic PDF. The ProdGen
context uses the new auxiliary proto variables to correctly
generate the correlation between imported and normalizing
observables.
o RooProdPdf
- Fix some outstanding link management problems
- Add new ctor with named arguments that allows to specify
correlated products
- Adjust product factorization to understand concept of 'imported'
dependents, which allows to split composite terms that would
otherwise be irriducible
- Add term grouping algorithm that groups together irriducible terms that
share dependents in mixed roles (normalizing vs imported) over which is
integrated. Such integrals can only be calculated properly if the
entire product of such terms is integrated rather than the terms
individually.
- Reorganize code a bit: break factorization, term grouping and
prefabrication of partial integral lists into several functions.

o RooSimultaneous
- Reimplement handling of normalization and other integrals using
the normalization list manager.
Each integration request to a RooSimultaneous now builds a list
of RooRealIntegral objects for all its components. The return
value is sampled from the integral object that corresponds to
the current value of the index state.
This new procedure makes simPdf->createProjection, used
often for likelihood projection plots, efficient and robust

CPUs and calculation of GOFs from simulatenous PDFs.
o New class RooAbsOptGoodnessOfFit
- Abstract base class for goodness-of-fit variables
that calculate the PDF value at each data point in the
given dataset. It implements various optimizations:
caching of constant terms, elimination of unused variables etc.
o RooAbsPdf
- Deploy new normalization integral manager RooNormManager
to cache multiple normalization integrals for a PDF.
This greatly increases the efficiency for certain situations
where PDFs are alternatingly called with 2 or more different
normalization choices

exits. This class sends termination signals when this
singleton class is deleted
o RooMath
- Activate CERF disk caching by default
o New class RooMinuit
- New seamless interface between RooFit objects and MINUIT
Class propagates information forth and back between RooAbsArg
objects and minuits internal memory buffer (e.g. parameter
values, errors, step sizes, constant status)
- This class minimizes any RooAbsReal function (doesn't need to
be a NLL or Chi2)
o Removed class RooNLLBinding
- Obsolete after introduction of RooNLLVar
o New class RooNLLVar
- Implementation for NLL of RooAbsOptGoodnessOfFit
o RooNameSet
- Fix memory leak
o New class RooNormManager
- New manager class for normalization/projection integrals for PDFs
This class matches RooArgSet pointer pairs to the integration
and normalization sets to previously registered integrals.
Multiple pointer pairs can point to the same integral (e.g.
pointer to different RooArgSets with the same contents) and
multiple integrals can be cached. This class doesn't create
the normalization integrals. It merely indicates if it has
one or not, and leaves it up to the owning class to create
and register new normalizations
o New class RooNormListManager
- Similar to RooNormManager, except that RooArgLists of normalization
integrals are caches instead of single integrals
o RooNormSetCache
- Rework functionality. This class, used by RooNorm(List)Manager
manages multiple redundant RooArgSet pointer pairs that represent
the same projection/normalization configuration
o RooProdPdf
- Almost complete rewrite in terms of RooNormListManager
o RooRealConstant
- Minor const changes
o RooRealIntegral
- Streamline iterator use: Create various interator in ctor
and reuse them in evaluate() instead of creating and deleting
them on the fly
o New class RooRealMPFE
- Front end for MultiProcessor calculations. Class RooRealMPFE
takes a RooAbsReal as argument and calculates it in separate
process. Calculations can be started asynchronously with
the calculate() call. The rest of the interface (and behaviour)
is identical to that of the original RooAbsReal.
o RooResolutionModel
- Deprecate getNormSpecial - superceded by RooNormManager
o RooSetProxy
- Implement addClone(const RooAbsCollection&,...)
o Removed class RooSimFitContext
- Obsolete - replaced by RooMinuit/RooNLLVar
o RooSimGenContext
- Fix memory leak
o RooSimultaneous
- remove obsolete fitContext() method
o RooTreeData
- Reimplement caching. Cached functions are now stored in
a separate tree in the dataset. Main benefit of the new
implementation is that caches can efficiently be reset
and refilled on the fly
o makedocs
- Add stanzas for new tutorial macros

o RooAbsCollection
- Add selectByName() member that accepts a comma separated list
of wildcard patterns to create a subset filled with the matching
elements
o RooAbsData
- Fix typo in print message
o RooAbsPdf
- Add new plotCompOn/plotCompSliceOn methods that take
a string wildcard expression or argset of components
to plot. Selected component may occur at any level in
the PDF tree
- Add component selector flag bit to support new component
plotting scheme
o RooAddPdf
- Change evaluate() to only include PDFs that have their
selection bit raised
- Remove old plotCompOn methods()
o RooFitContext
- Store asymmetic errors in parameter RooRealVars, if they
are available
o RooMCStudy
- Adapt to changes in RooRealVar. Ensure persistence of
symmetric and asymmetric errors of RRVs in parameter dataset
o RooRealVar
- Add asymmetric errors and accessor/modifier functions.
Asym. errors are stored and managed independently from
the existing symmetric error
- Introduce hasError(), hasAsymError() functions indicating
if an error has been set to the object.
- Adapt writeToStream/readFromStream to process asymmetric
errors. Split 'L(lo-hi:bins)' token in 'L(lo-hi) B(bins)'
tokens so that bin specification becomes optional. Change
logic for error printing: instead of requiring
(!constant || error>0) simply require hasError()
- By default no longer persist error(s) along with value
when attached to a dataset. To request persistence of
symmetric error, set "StoreError" attribute. To request
persistence of asym. error, set "StoreAsymError" attribute.
o RooSimultaneous
- Deprecate specialized plotCompOn/plotCompSliceOn functions
- Modify regular plotOn to plot a temporary RooAddPdf, with the
coefficients determined from the fractions of the index
state occurring the in the prototype dataset

A large number of small fixes and improvements
o Roo1DTable
- Modify Print() behaviour. Standard print will
only show non-empty fields, verbose shows all fields
o RooAbsArg
- Change getParameters so that it can accept 0 as
dataset pointer (implies no dependents)
o RooAbsPdf
- Follow plotOn() changes in RooAbsReal
o RooAbsReal
- Add optional const RooArgSet* projData argument to
plotOn(). Projected dependents that appears in this
dataset, if specified, will be projection via summation
over data instead of integration.
- Add clipInvalid option to bindVars() and propagate to
RooRealBinding
- Modify cleanBranchName() to truncate 'clean names'
(which are used for the TTree branch) to 63 chars
as cannot handle such cases (SEGV). In case name
is longer than 63 chars, truncate name at 46 chars
and suffix with _crc followed by hex representation
of CRC32 checksum of the full name.
- Add crc32() method to calculate the checksum of a string
o RooAddModel,RooAddPdf
- Do not evaluate PDF components multiplied by a zero coefficient
o RooAddPdf
- Fix DIV0 in analyticalIntegral if number of expected events
for all PDFs combined totals zero
o RooArgSet
- Add ability to readFromStream and readFromFile to optionally
flag read arguments with a user specified attribute
(Mostly useful to determine which elements have _not_ been read)
o RooConvolutedPdf
- Change declareBasis() signature from a RooArgSet& to a RooArgList&
to correctly handle cases where the names of parameters are identical
(e.g. tau=zero and dm=zero for prompt background models)
- Expand logic in RooGenContext. Add additional requirement for
use of optimized generator context: both the physics pdf and
the resolution model must support direct generation of the
convolution variable.
(Still have to fix RooAddModel/Pdf for cases where all components
can do direct generation)
o RooCurve
- Deploy RooRealBinding::clipInvalid feature to zero plotted functions
outside the validity range of their dependents
- Add extra points at (xlo,0) and (xhi,0) to obtain correct filling
pattern when using the 'F' draw option.
o RooCustomizer
- Add warnings for multiple split or replace rules on the same leaf
o RooDataSet
- Make read() take a const RooArgList& instead of a RooArgList&
and immediately make temporary copy for internal use.
- All constructors with string based cut: add default empty cut.
o RooFitContext
- Ctor: Compare limits on dependents in PDF and dataset if limits
of PDF are smaller and fully contained in those of the dataset,
adjust the dataset ranges in the internal copy and reject events
outside the PDF limits. If PDF ranges are not identical or fully
contained in dataset limits, give error message and abort.
- In fit() fix handling of parameters handed to TMinuit: set pmin/pmax
to the parameter value for constant parameters. For floating parameters
with open limits and without error, use 1/10 of the plot range
instead of 1/10 of the fit range.
o RooFormula,RooFormulaVar
- Change RooArgSet to RooArgList to pass formula parameters.
This allows construction of formulas with ordinal references
for list of parameters with multiple occurrences of the same
variable.
o RooRealBinding
- Add clipInvalid option, specified in ctor. If set, loadValues()
will first check if the values to be loaded are in the limits
of the bound objects dependents. If not the values are not loaded
and an invalid flag is set. If the invalid flag is set operator()
will return 0.
o RooRealVar
- Add various 'named parameter' functions on a trial basis
o RooSimFitContext
- Gracefully handle RooSimultaneous PDFs with missing PDFs.
o RooSimGenContext
- Forgot to set index state in theEvent RooArgSet when generating
the index category
- Remove forced normalization of index state in evaluate()
- Remove dummy plotOn() method and specialized plotOn() with data
method as projection over the index state can now be handled
the regular plotOn method. Overload RooAbsPdf::plotOn to
force caller to specify projection dataset for the index category
if projection over the index category is requested
o RooTable
- Remove print(), add default Print(Option_t *), and reimplement
printing via inheritance from RooPrintable
o RooTreeData
- In loadValues(RooTreeData*) explicitly check isValid() of
each element of _vars after copying. If any is invalid,
reject the event.
- In table() change simple clone of tableVar to deep clone.
Implement use of optional cut string (accidentally omitted sofar)
o RooTruthModel
- Add highly trivial direct generator for the convolution variable
o RooDataProjBinding
- New lightweight binding between an RooAbsReal and a dataset
that returns the projection of the real over the dataset
via summation. If the dataset only contains category variables
an supercategory of all the datasets categories is created
and the data is summed (with appropriate weights) over the
supercategory states instead of over every event.

plotSliceOn(frame,sliceset,...) - Partially projected plotting
plotAsymOn(frame,asymCat,...) - Asymmetry plotting
(for any 'sign-type' cat. variable)
- Projection logic moved from RooCurve::ctor to plotOn(),
rearranged to use createProjection()
- Introduce some protected helper functions for plotting

Binned data reorganization
--------------------------
o RooAbsArg,RooAbsCategory,RooAbsReal,RooAbsRealLValue,RooAbsCategoryLValue,RooAbsLValue,RooRealVar
- Introduce the concept of 'fit bins' for the purpose of binned fits
So far we have been abusing the plot bins for this purpose but this
will ultimately lead to confusion
RooAbsLValue now defines 5 abstract methods to access the fit bin interface
setFitBin(), getFitBin(), numFitBins(), getFitBinWidth(), createFitBinIterator()
which are implemented in RooAbsCategoryLValue and RooAbsRealLValue
RooRealVar holds the fitBins data member.
o RooDataHist
- Change to use fit bins and range instead of plot bins and range for
binning a dataset
- Add new sum() methods implementing full and partial summation of
of the dataset contents, optionally accounting for bin volume correction
o RooHistPdf
- New PDF constructed from a RooDataHist implements n-dimensional
PDFs constructed from an equivalent histogram. All dimensions can
be either real of discrete
- All partial and full integrations are implemented using the new
RooDataHist::sum() methods.
Plotting reorganization (part 1)
--------------------------------
o RooPlot,RooHist,RooCurve,RooPlotable
- Store the two components of the normalization #events and binWidth
seperately
- Replace getFitRangeNorm() method with getFitRangeNEvt() and getFitRangeBinW()
methods
- Adapt updateFitRangeNorm() to store components of normalization separately
o RooAbsReal ( & RooSimultaneous)
- Add extra enum to plotOn() indicating interpretation of given scalefactor
Raw -> Apply scale factor without any other adjustments
Relative -> Apply scale factor after default normalization adjustment (old implementation)
NumEvent -> Interpret scale factor as number of events to normalize to
For RooAbsReals that are not a RooAbsPdf, the Raw procedure is always applied
Some more reorganization will follow in this area
o RooFormulaVar
- Take out dummy analytical integration definition now that plotOn will do the
right thing by default
Misc. fixes
-----------
o RooAbPdf
- Fix normalization bug in analytical integration by introducing overloaded
analyticalIntegralWN, which returns analyticalIntegral()/getNorm()
instead of just analyticalIntegral()
o RooAddPdf
- Eliminate now obsolete addPdf() and addLastPdf() member functions

Major cleanup in integration of normalization functions
Miscellaneous small improvements and fixes
o Roo1DTable
- Add get(),getFrac() methods to retrieve contents
o RooAbsCollection
- Add selectCommon() method to create new collection
containing args common to two sets
o RooAbsData
- Minor const-correctness changes
o RooAbsReal
- Rearrangement of getAnalyticalIntegral/analyticalIntegral entry points.
Both functions now exist with and without a 'const RooArgSet* normSet'
The functions with normSet are used by RooRealIntegral, and its default
implementation handle the pass-through scenario (code 0 = getVal(normSet))
and defers other codes to the non-normSet variant.
Simple PDFs should implement the non-normSet variants, as they used
to do sofar, except they no longer should (or are able to) process
the passthrough scenario.
Advanced PDFs such as RooAdd,ProdPdf, RooConvolutedPdf that implement
complex integration schemes that depend on the exact normSet configuration
reimplement the getAI,aI functions with normSet.
o RooResolutionModel, RooAddModel
- Implement (or forward in case of RooAddModel) new getNormSpecial method.
This function is identical in functionality to RooAbsPdf::getNorm()
except that it caches a separate copy of the normalization integral.
This member is introduced for the benefit of RooConvolutedPdf::analyticalIntegral
which, in case of a normalized integration, alternatingly calls two different
normalizations. In the original single cache code, this would lead to
100% caching failure and 300% slowdown of the code. getNormSpecial is
protected for access by RooConvolutedPdf only.
o RooAddPdf,RooProdPdf,RooSimultaneous,RooConvolutedPdf
- Re-implement distributed analytic integration bookkeeping using
the auxiliary RooAICRegistry class, which keeps track of multiple
analytical integration codes (hence AIC)
o RooAICRegistry
- New auxiliary class to faciliate the management of distributed analytic
integration.
o RooArgSet
- Minor printing fix
o RooConvolutedPdf
- Complete rewrite of handling of analytical integrations. For RCP objects
analytical integrations are not all necesarily analytic, but include
integrations deferred to convolution objcts. Analytical integrations
are split off for coefficient terms. Complete double bookkeeping introduced
for 'integration' part of analytic integration and 'normalization' part
of integration, each of which can have a different argSet to defer
to the convolution objects and a different coefficient analytical integration
code. Current implementation is believed to be complete.
o RooFormulaVar
- Follow signature change of getAnalyticalIntegral/analyticalIntegral
o RooMath
- Implement file cacheing scheme for complex error function lookup table.
To invoke persistent caching, call RooMath::cacheCERF(kTRUE) prior to
use
o RooRealAnalytic
- Store and forward normalization set to analyticalIntegral call of
bound RooAbsReal
o RooSimultanous
- Implement new plotOn() method, taking a dataSet which can correctly
project a RooSimultaneous. The code is mostly copied from RooAbsReal::
plotOn, except that the plotted pdf is constructed as a RooAddPdf
of the RooSimultaneous components, weighted by the fractions found
in the passed dataset
o RooTreeData
- Small const-correctness fixes

o RooAbsPdf
- Hold in addition to _lastDataSet a RooNameSet with the names
of the members of that dataset. If (_lastDataSet != dset) in
syncNormalization, first check if contents of _lastDataSet
is different from dset before redoing the normalization.
If >1 RooConvolutedPdf share a RooResolutionModel, the resolution
model will receive syncNormalization calls for the dummy data
sets contained in all RooConvolutedPdf. All these sets contain
most likely the same set of variables and a recalculation is
thus not necessary.
We cannot use _lastDataSet->get() to get the name list of the
previously used data set because that dataset might no longer
exist
o RooAddModel,RooAddPdf,RooProdPdf,RooSimultaneous
- Change signature of selfNormalized(const RooArgSet* depList)
to selfNormalized(). Partial self-normalization is an ill-defined
concept at this level. The original reason for introducing this
(RooConvolutedPdf objects insisting on handling integrals delegated
to their convolution integrals) has meanwhile been replace with the
forcedAnalyticalInt() method

o All RooAbsArg derived classes
- Change clone() to clone(const char* newname=0) to facilitate cloning with alternate names.
o RooAbsArg
- Add another layer to link management: operMode. If operMode=auto, all behaves
as before. If operMode=AClean, the arg assumes the cache is always clean and
getValueDirty() will always return false. If operMode=ADirty, the arg assumes
the cache is always dirty and isValueDirty will always return true.
The ADirty and AClean modes are used by the optimizer in the fit context
to shut down link management (and save time) for cases where the arg is
always dirty after a dirty state propagation from one of the dependents.
The AClean mode is used similarly for args that are cached in the dataset
The setOperMode() member is protected as care should be taken in switching modes.
It is the callers responsability to ensure that the claimed state (especially
in case of AClean) is indeed correct.
- Split setValueDirty(Bool_t flag) in setValueDirty() and clearValueDirty().
The latter is trivial and can be inlined to save time.
- redirectServers() now has an optional nameChange flag that allows to reconnect
to servers with different names. If the option is enabled, a link will be reconnected
to the server with a 'ORIGNAME:<servername>' attribute instead of a server with <servername>
This feature is used by RooPdfCustomizer.
- Added recursive printDirty() member that listed dirty state of arg and all its servers.
- Add sorting capability by implementing IsSortable() and CompareTo() members.
Sorting will result in alphabetical ordering by object name.
o RooAbsCategory
- Change tree attachement: store both label and index fields in tree instead of
just the index field. Looking up the corresponding label turns out to be rather
expensive, especially if many state are defined.
- The postTreeLoadHook() mechanism that formerly implemented the index lookup
has been abandoned completely (save 1 virtual function call per data set load).
o RooAbsPdf
- Change function call structure of eval tracing a bit to reduce the number
of calls per trace from virtual calls to 1 concrete call.
- In syncNormalization, if the data sets are different, first check if they
also have a different contents before processing the change. (Save multiple
identical normalization calculations for cases were a resolution model is
shared by >1 RooConvolutedPdf. (WVE Caveat: this has some problems: code will
die if cached data set is deleted before pdf. Will fix this soon)
Install pre- and postSyncNormalizationHook functions that can be used to customize
the call. Used by RooConvolutedPdf to create/update dummy data sets used to
push down partial integrations to the convolution integrals.
- Move nLogLikelihood to RooFitContext
o RooAbsReal
- in attachToTree(), mangle name of object in tree to exclude math symbols that
are interpreted by root in certain circumstances
o RooAddModel
- Store coef and proxy iterators in class instead of creating them on the fly each
time in evaluate()
- Release ownership of proxied resolution models in the copy constructor. If the
AddModel is copied, the proxied components will be owned by the list created
by RooArgSet::snapshot().
- Include name of AddModel owner in component resolution model to avoid multiple
identically named object in certain PDF configurations
- Export 'master list' of combined normalization leaf node servers of all components.
The convolutedPdf needs this for it's own dependency calculation
o RooArgSet
- Add silent option to remove()
o RooCatType
- Store name in char[] instead of in TNamed::fName (a TString) so that
the name can be attached to a Tree. (A TString is not a TObject)
o RooConvolutedPdf
- Push integration of all dependents that do not overlap with the coefficients
to the convolution integrals, instead of just the convolution variable
o RooDataSet
- Add new constructor that allows to specify the cut as a RooFormulaVar object
instead of a string. This allows to cut on function arguments that are not
part of the data set
- Allow to switch off dirty state propagation after a row-load operation
(can be used in certain optimization scenarios)
o RooFitContext
- Add option to not clone either dataset or pdf on construction
- Remove non-RooRealVar parameters from master parameter list to prevent that
MINUIT chokes on them
- Sort minuit parameter list alphabetically
- Add cache optimization option, which shuts down all link management for the
all pdf value components (not normalization). This can save a significant amount
of time, especially for very complex PDFs as the number dirty propagations scales
with the square of the number of nodes. Use newly introduces AClean and ADirty
modes to ensure proper evaluation of PDF nodes
- Add option to execute migrad with 'strategy 0', which skips the evaluation of
the error matrix. (Saves time if you do that later with HESSE anyway)
- Move nLoglikelihood() function from RooAbsPdf to here.
- Improve readability of messages in fitting in log-mode: print on screen only value
and name of parameters that change instead of dumping all their values all the time.
The old format has been retained in the log file, to allow automated processing of such files.
o RooFormulaVar
- Also update _origList on a serverRedirect
- Export ok() function of RooFormula (indicates if expression compiled ok)
o RooMath
- Add fast, interpolated, complex error function. Upon first use separate lookup tables
are filled for the im and re part of the complex error function. New functions will
do a 2nd or 3rd order 2D interpolation (depending on z) of the lookup table for either
the re part, the im part or both. Precision is better that 1e-6 in ~99% of covered
phase space. Imprecise regions are in problematic part of cErf where giant fluctuations
occur. Typical likelihood calculated with interpolated cErf agrees in the first 10
significant digits. Interpolation function is ~3.5 times faster than original CWERF
implementation, when only 1 component (im/re) of cErf is needed (most cases).
Interpolation function taken from Numerical Recipes and further optimized for
fixed grid assumption
o RooMappedCategory
- Clone also MapCatEntries in RooMappedCategory copy ctor
o RooProdPdf
- Store coef and proxy iterators in class, instead of instantiating them on the fly
in evaluate()
- Add optional cutoff parameter. If running PDF product goes below cutoff, product
calculation is terminated (default value=0, very small values like 1e-15 can be
benificial in case of wide window calculations a Gaussian + something flattish)
o RooRealIntegral
- Allow and perform integration over variables that input function doesn't depend
on (multiply integral by product of ranges of such variables)
o RooResolutionModel
- In convolution(): append name of owner to convolution, to avoid non-identical
convolutions with the same name in certain PDF configurations
- Forward redirectServers to basis function
o RooSimultaneous
- Overload fitTo() to create a RooSimFitContext instead of a RooFitContext
which allows certain additional optimizations specific to RooSimultaneous
- Normalize by the number of registered PDFs instead of the number of types
defined by the index category (allows to to partial fits)
o RooStreamParser
- Take '}' and ';' out of the default punctuation list so that RooSuperCategory
state names do not get broken up into multiple tokens
o RooThresholdCategory
- New category class that applies a series of thresholds on a RooRealVar to
define its state.
o RooThreshEntry
- Support class for RooThresholdCategory
o RooPdfCustomizer
- Utility class that serves a factory to build multiple PDFs from a single prototype
that have slightly different leaf nodes.
The class takes a proto type and a master index category in the constructor.
A series of splitting rules determines how given leaf nodes are to be 'split'
over the master index category or a subset of the master index (in case the master
index is a RooSuperCategory)
The instiated 'split' leaf nodes are put in an argset referenced in the constructor.
and the owner of the argset is responsible for deleting them (or passing them on
to another RooPdfCustomizer). The instantiated branch nodes are owned by the customizer.
o RooSimFitContext
- Specialized fit context, derived from RooFitContext, that optimizes the likelihood
calculation in case the top level pdf is a RooSimultaneous. The original data
set is broken into pieces, corresponding to a single state of the RooSimultaneous
index category and those data subsets are combined with the corresponding PDF branches
of the RooSimultaneous to form an array of regular RooFitContexts. The total likelihood
is calculated as the sum of the likelihoods from the array of fit contexts.
The NLL output from each subcontext is cached and only recalculated if a parameter
that the PDF of that subcontexts depends on, is changed.
This form of calculation is very efficient for fits where the correlation matrix has
a block diagonal form. The CPU time in RooSimFitContext scales (approximately) with
the number of elements in the block diagonal elements instead of with the total number
of elements.
o Nearly all classes
- A large number of minor bugs has been fixed and many functions
that are called very frequently have been inlined, made non-virtual or
have been eliminated, following the result of repeated profiler studies.
