RooAbsPdf Class Reference

RooAbsPdf is the abstract interface for all probability density functions The class provides hybrid analytical/numerical normalization for its implementations, error tracing and a MC generator interface.

A minimal implementation of a PDF class derived from RooAbsPdf should overload the evaluate() function. This functions should return PDFs value.

Normalization/Integration

Although the normalization of a PDF is an integral part of a probability density function, normalization is treated separately in RooAbsPdf. The reason is that a RooAbsPdf object is more than a PDF: it can be a building block for a more complex, composite PDF if any of its variables are functions instead of variables. In such cases the normalization of the composite may not be simply the integral over the dependents of the top level PDF as these are functions with potentially non-trivial Jacobian terms themselves. Therefore

–> No explicit attempt should be made to normalize the functions output in evaluate().**

In addition, RooAbsPdf objects do not have a static concept of what variables are parameters and what variables are dependents (which need to be integrated over for a correct PDF normalization). Instead the choice of normalization is always specified each time a normalized values is requested from the PDF via the getVal() method.

RooAbsPdf manages the entire normalization logic of each PDF with help of a RooRealIntegral object, which coordinates the integration of a given choice of normalization. By default, RooRealIntegral will perform a fully numeric integration of all dependents. However, PDFs can advertise one or more (partial) analytical integrals of their function, and these will be used by RooRealIntegral, if it determines that this is safe (i.e. no hidden Jacobian terms, multiplication with other PDFs that have one or more dependents in commen etc)

To implement analytical integrals, two functions must be implemented. First,

Int_t getAnalyticalIntegral(const RooArgSet& integSet, RooArgSet& anaIntSet)

advertises the analytical integrals that are supported. 'integSet' is the set of dependents for which integration is requested. The function should copy the subset of dependents it can analytically integrate to anaIntSet and return a unique identification code for this integration configuration. If no integration can be performed, zero should be returned. Second,

Double_t analyticalIntegral(Int_t code)

Implements the actual analytical integral(s) advertised by getAnalyticalIntegral. This functions will only be called with codes returned by getAnalyticalIntegral, except code zero.

The integration range for real each dependent to be integrated can be obtained from the dependents' proxy functions min() and max(). Never call these proxy functions for any proxy not known to be a dependent via the integration code. Doing so may be ill-defined, e.g. in case the proxy holds a function, and will trigger an assert. Integrated category dependents should always be summed over all of their states.

Direct generation of observables

Any PDF dependent can be generated with the accept/reject method, but for certain PDFs more efficient methods may be implemented. To implement direct generation of one or more observables, two functions need to be implemented, similar to those for analytical integrals:

Int_t getGenerator(const RooArgSet& generateVars, RooArgSet& directVars) and void generateEvent(Int_t code)

The first function advertises observables that can be generated, similar to the way analytical integrals are advertised. The second function implements the generator for the advertised observables

The generated dependent values should be store in the proxy objects. For this the assignment operator can be used (i.e. xProxy = 3.0 ). Never call assign to any proxy not known to be a dependent via the generation code. Doing so may be ill-defined, e.g. in case the proxy holds a function, and will trigger an assert

RooAbsReal * RooAbsPdf::createCdf ( const RooArgSet iset,
const RooArgSet nset = RooArgSet() 
)

Create a cumulative distribution function of this p.d.f in terms of the observables listed in iset.

If no nset argument is given the c.d.f normalization is constructed over the integrated observables, so that its maximum value is precisely 1. It is also possible to choose a different normalization for multi-dimensional p.d.f.s: eg. for a pdf f(x,y,z) one can construct a partial cdf c(x,y) that only when integrated itself over z results in a maximum value of 1. To construct such a cdf pass z as argument to the optional nset argument

virtual

Construct representation of -log(L) of PDFwith given dataset.

If dataset is unbinned, an unbinned likelihood is constructed. If the dataset is binned, a binned likelihood is constructed.

The following named arguments are supported

ConditionalObservables(const RooArgSet& set) – Do not normalize PDF over listed observables Extended(Bool_t flag) – Add extended likelihood term, off by default Range(const char* name) – Fit only data inside range with given name Range(Double_t lo, Double_t hi) – Fit only data inside given range. A range named "fit" is created on the fly on all observables. Multiple comma separated range names can be specified. SumCoefRange(const char* name) – Set the range in which to interpret the coefficients of RooAddPdf components NumCPU(int num, int strat) – Parallelize NLL calculation on num CPUs

                               Strategy 0 = RooFit::BulkPartition (Default) --> Divide events in N equal chunks 
                               Strategy 1 = RooFit::Interleave --> Process event i%N in process N. Recommended for binned data with 
                                            a substantial number of zero-bins, which will be distributed across processes more equitably in this strategy
                               Strategy 2 = RooFit::SimComponents --> Process each component likelihood of a RooSimultaneous fully in a single process
                                            and distribute components over processes. This approach can be benificial if normalization calculation time
                                            dominates the total computation time of a component (since the normalization calculation must be performed
                                            in each process in strategies 0 and 1. However beware that if the RooSimultaneous components do not share many
                                            parameters this strategy is inefficient: as most minuit-induced likelihood calculations involve changing
                                            a single parameter, only 1 of the N processes will be active most of the time if RooSimultaneous components
                                            do not share many parameters
                               Strategy 3 = RooFit::Hybrid --> Follow strategy 0 for all RooSimultaneous components, except those with less than
                                            30 dataset entries, for which strategy 2 is followed.

Optimize(Bool_t flag) – Activate constant term optimization (on by default) SplitRange(Bool_t flag) – Use separate fit ranges in a simultaneous fit. Actual range name for each subsample is assumed to by rangeName_{indexState} where indexState is the state of the master index category of the simultaneous fit Constrain(const RooArgSet&pars) – For p.d.f.s that contain internal parameter constraint terms, only apply constraints to given subset of parameters ExternalConstraints(const RooArgSet& ) – Include given external constraints to likelihood GlobalObservables(const RooArgSet&) – Define the set of normalization observables to be used for the constraint terms. If none are specified the constrained parameters are used GlobalObservablesTag(const char* tagName) – Define the set of normalization observables to be used for the constraint terms by a string attribute associated with pdf observables that match the given tagName Verbose(Bool_t flag) – Constrols RooFit informational messages in likelihood construction CloneData(Bool flag) – Use clone of dataset in NLL (default is true) Offset(Bool_t) – Offset likelihood by initial value (so that starting value of FCN in minuit is zero). This can improve numeric stability in simultaneously fits with components with large likelihood values

Fit PDF to given dataset.

If dataset is unbinned, an unbinned maximum likelihood is performed. If the dataset is binned, a binned maximum likelihood is performed. By default the fit is executed through the MINUIT commands MIGRAD, HESSE in succession.

The following named arguments are supported

Options to control construction of -log(L)

ConditionalObservables(const RooArgSet& set) – Do not normalize PDF over listed observables Extended(Bool_t flag) – Add extended likelihood term, off by default Range(const char* name) – Fit only data inside range with given name Range(Double_t lo, Double_t hi) – Fit only data inside given range. A range named "fit" is created on the fly on all observables. Multiple comma separated range names can be specified. SumCoefRange(const char* name) – Set the range in which to interpret the coefficients of RooAddPdf components NumCPU(int num, int strat) – Parallelize NLL calculation on num CPUs

                               Strategy 0 = RooFit::BulkPartition (Default) --> Divide events in N equal chunks 
                               Strategy 1 = RooFit::Interleave --> Process event i%N in process N. Recommended for binned data with 
                                            a substantial number of zero-bins, which will be distributed across processes more equitably in this strategy
                               Strategy 2 = RooFit::SimComponents --> Process each component likelihood of a RooSimultaneous fully in a single process
                                            and distribute components over processes. This approach can be benificial if normalization calculation time
                                            dominates the total computation time of a component (since the normalization calculation must be performed
                                            in each process in strategies 0 and 1. However beware that if the RooSimultaneous components do not share many
                                            parameters this strategy is inefficient: as most minuit-induced likelihood calculations involve changing
                                            a single parameter, only 1 of the N processes will be active most of the time if RooSimultaneous components
                                            do not share many parameters
                               Strategy 3 = RooFit::Hybrid --> Follow strategy 0 for all RooSimultaneous components, except those with less than
                                            30 dataset entries, for which strategy 2 is followed.

SplitRange(Bool_t flag) – Use separate fit ranges in a simultaneous fit. Actual range name for each subsample is assumed to by rangeName_{indexState} where indexState is the state of the master index category of the simultaneous fit Constrained() – Apply all constrained contained in the p.d.f. in the likelihood Contrain(const RooArgSet&pars) – Apply constraints to listed parameters in likelihood using internal constrains in p.d.f GlobalObservables(const RooArgSet&) – Define the set of normalization observables to be used for the constraint terms. If none are specified the constrained parameters are used ExternalConstraints(const RooArgSet& ) – Include given external constraints to likelihood Offset(Bool_t) – Offset likelihood by initial value (so that starting value of FCN in minuit is zero). This can improve numeric stability in simultaneously fits with components with large likelihood values

Options to control flow of fit procedure

Minimizer(type,algo) – Choose minimization package and algorithm to use. Default is MINUIT/MIGRAD through the RooMinimizer interface, but others can be specified (through RooMinimizer interface). Select OldMinuit to use MINUIT through the old RooMinuit interface

   Type         Algorithm
   ------       ---------

   Minuit2      migrad, simplex, minimize, scan
   GSLMultiMin  conjugatefr, conjugatepr, bfgs, bfgs2, steepestdescent
   GSLSimAn     -

InitialHesse(Bool_t flag) – Flag controls if HESSE before MIGRAD as well, off by default Optimize(Bool_t flag) – Activate constant term optimization of test statistic during minimization (on by default) Hesse(Bool_t flag) – Flag controls if HESSE is run after MIGRAD, on by default Minos(Bool_t flag) – Flag controls if MINOS is run after HESSE, off by default Minos(const RooArgSet& set) – Only run MINOS on given subset of arguments Save(Bool_t flag) – Flac controls if RooFitResult object is produced and returned, off by default Strategy(Int_t flag) – Set Minuit strategy (0 through 2, default is 1) FitOptions(const char* optStr) – Steer fit with classic options string (for backward compatibility). Use of this option excludes use of any of the new style steering options.

SumW2Error(Bool_t flag) – Apply correaction to errors and covariance matrix using sum-of-weights covariance matrix to obtain correct error for weighted likelihood fits. If this option is activated the corrected covariance matrix is calculated as Vcorr = V C-1 V, where V is the original covariance matrix and C is the inverse of the covariance matrix calculated using the weights squared

Options to control informational output

Verbose(Bool_t flag) – Flag controls if verbose output is printed (NLL, parameter changes during fit Timer(Bool_t flag) – Time CPU and wall clock consumption of fit steps, off by default PrintLevel(Int_t level) – Set Minuit print level (-1 through 3, default is 1). At -1 all RooFit informational messages are suppressed as well Warnings(Bool_t flag) – Enable or disable MINUIT warnings (enabled by default) PrintEvalErrors(Int_t numErr) – Control number of p.d.f evaluation errors printed per likelihood evaluation. A negative value suppress output completely, a zero value will only print the error count per p.d.f component, a positive value is will print details of each error up to numErr messages per p.d.f component.

Plot (project) PDF on specified frame.

If a PDF is plotted in an empty frame, it will show a unit normalized curve in the frame variable, taken at the present value of other observables defined for this PDF

If a PDF is plotted in a frame in which a dataset has already been plotted, it will show a projected curve integrated over all variables that were present in the shown dataset except for the one on the x-axis. The normalization of the curve will also be adjusted to the event count of the plotted dataset. An informational message will be printed for each projection step that is performed

This function takes the following named arguments

Projection control

Slice(const RooArgSet& set) – Override default projection behaviour by omittting observables listed in set from the projection, resulting a 'slice' plot. Slicing is usually only sensible in discrete observables. The slice is position at the 'current' value of the observable objects

Slice(RooCategory& cat, – Override default projection behaviour by omittting specified category const char* label) observable from the projection, resulting in a 'slice' plot. The slice is positioned at the given label value. Multiple Slice() commands can be given to specify slices in multiple observables

Project(const RooArgSet& set) – Override default projection behaviour by projecting over observables given in set and complete ignoring the default projection behavior. Advanced use only.

ProjWData(const RooAbsData& d) – Override default projection technique (integration). For observables present in given dataset projection of PDF is achieved by constructing an average over all observable values in given set. Consult RooFit plotting tutorial for further explanation of meaning & use of this technique

ProjWData(const RooArgSet& s, – As above but only consider subset 's' of observables in dataset 'd' for projection through data averaging const RooAbsData& d)

ProjectionRange(const char* rn) – Override default range of projection integrals to a different range speficied by given range name. This technique allows you to project a finite width slice in a real-valued observable

NumCPU(Int_t ncpu) – Number of CPUs to use simultaneously to calculate data-weighted projections (only in combination with ProjWData)

Misc content control

PrintEvalErrors(Int_t numErr) – Control number of p.d.f evaluation errors printed per curve. A negative value suppress output completely, a zero value will only print the error count per p.d.f component, a positive value is will print details of each error up to numErr messages per p.d.f component.

EvalErrorValue(Double_t value) – Set curve points at which (pdf) evaluation error occur to specified value. By default the function value is plotted.

Normalization(Double_t scale, – Adjust normalization by given scale factor. Interpretation of number depends on code: Relative: ScaleType code) relative adjustment factor, NumEvent: scale to match given number of events.

Name(const chat* name) – Give curve specified name in frame. Useful if curve is to be referenced later

Asymmetry(const RooCategory& c) – Show the asymmetry of the PDF in given two-state category [F(+)-F(-)] / [F(+)+F(-)] rather than the PDF projection. Category must have two states with indices -1 and +1 or three states with indeces -1,0 and +1.

ShiftToZero(Bool_t flag) – Shift entire curve such that lowest visible point is at exactly zero. Mostly useful when plotting -log(L) or chi^2 distributions

AddTo(const char* name, – Add constructed projection to already existing curve with given name and relative weight factors double_t wgtSelf, double_t wgtOther)

Plotting control

DrawOption(const char* opt) – Select ROOT draw option for resulting TGraph object

LineStyle(Int_t style) – Select line style by ROOT line style code, default is solid

LineColor(Int_t color) – Select line color by ROOT color code, default is blue

LineWidth(Int_t width) – Select line with in pixels, default is 3

FillStyle(Int_t style) – Select fill style, default is not filled. If a filled style is selected, also use VLines() to add vertical downward lines at end of curve to ensure proper closure FillColor(Int_t color) – Select fill color by ROOT color code

Range(const char* name) – Only draw curve in range defined by given name

Range(double lo, double hi) – Only draw curve in specified range

VLines() – Add vertical lines to y=0 at end points of curve

Precision(Double_t eps) – Control precision of drawn curve w.r.t to scale of plot, default is 1e-3. Higher precision will result in more and more densely spaced curve points

Invisible(Bool_t flag) – Add curve to frame, but do not display. Useful in combination AddTo()

VisualizeError(const RooFitResult& fitres, Double_t Z=1, Bool_t linearMethod=kTRUE) – Visualize the uncertainty on the parameters, as given in fitres, at 'Z' sigma'

VisualizeError(const RooFitResult& fitres, const RooArgSet& param, Double_t Z=1, Bool_t linearMethod=kTRUE) ; – Visualize the uncertainty on the subset of parameters 'param', as given in fitres, at 'Z' sigma'

Details on error band visualization

By default (linMethod=kTRUE) a linearized error is shown which is calculated as follows T error(x) = Z* F_a(x) * Corr(a,a') F_a'(x)

where F_a(x) = [ f(x,a+da) - f(x,a-da) ] / 2, with f(x) the plotted curve and 'da' taken from the fit result Corr(a,a') = the correlation matrix from the fit result Z = requested significance 'Z sigma band'

The linear method is fast (required 2*N evaluations of the curve, where N is the number of parameters), but may not be accurate in the presence of strong correlations (~>0.9) and at Z>2 due to linear and Gaussian approximations made

Alternatively (linMethod=kFALSE), a more robust error is calculated using a sampling method. In this method a number of curves is calculated with variations of the parameter values, as drawn from a multi-variate Gaussian p.d.f. that is constructed from the fit results covariance matrix. The error(x) is determined by calculating a central interval that capture N% of the variations for each valye of x, where N% is controlled by Z (i.e. Z=1 gives N=68%). The number of sampling curves is chosen to be such that at least 30 curves are expected to be outside the N% interval, and is minimally 100 (e.g. Z=1->Ncurve=100, Z=2->Ncurve=659, Z=3->Ncurve=11111) Intervals from the sampling method can be asymmetric, and may perform better in the presence of strong correlations, but may take (much) longer to calculate
