RooAbsReal Class Referenceabstract

RooAbsReal is the common abstract base class for objects that represent a real value and implements functionality common to all real-valued objects such as the ability to plot them, to construct integrals of them, the ability to advertise (partial) analytical integrals etc.

Implementation of RooAbsReal may be derived, thus no interface is provided to modify the contents.

Attach object to a branch of given TTree.

By default it will register the internal value cache RooAbsReal::_value as branch buffer for a Double_t tree branch with the same name as this object. If no Double_t branch is found with the name of this object, this method looks for a Float_t Int_t, UChar_t and UInt_t branch in that order. If any of these are found the buffer for that branch is set to a correctly typed conversion buffer in this RooRealVar. A flag is set that will cause copyCache to copy the object value from the appropriate conversion buffer instead of the _value buffer.

Create an object that represents the integral of the function over one or more observables listed in iset The actual integration calculation is only performed when the return object is evaluated.

The name of the integral object is automatically constructed from the name of the input function, the variables it integrates and the range integrates over. If nset is specified the integrand is request to be normalized over nset (only meaningful when the integrand is a pdf). If rangename is specified the integral is performed over the named range, otherwise it is performed over the domain of each integrated observable. If cfg is specified it will be used to configure any numeric integration aspect of the integral. It will not force the integral to be performed numerically, which is decided automatically by RooRealIntegral

const RooCmdArg arg8 = RooCmdArg::none() 
)

Create an object that represents the running integral of the function over one or more observables listed in iset, i.e.

int[x_lo,x] f(x_prime) dx_prime

The actual integration calculation is only performed when the return object is evaluated. The name of the integral object is automatically constructed from the name of the input function, the variables it integrates and the range integrates over. The default strategy to calculate the running integrals is

  • If the integrand (this object) supports analytical integration, construct an integral object that calculate the running integrals value by calculating the analytical integral each time the running integral object is evaluated
  • If the integrand (this object) requires numeric integration to construct the running integral create an object of class RooNumRunningInt which first samples the entire function and integrates the sampled function numerically. This method has superior performance as there is no need to perform a full (numeric) integration for each evaluation of the running integral object, but only when one of its parameters has changed.

The choice of strategy can be changed with the ScanAll() argument, which forces the use of the scanning technique implemented in RooNumRunningInt for all use cases, and with the ScanNone() argument which forces the 'integrate each evaluation' technique for all use cases. The sampling granularity for the scanning technique can be controlled with the ScanParameters technique which allows to specify the number of samples to be taken, and to which order the resulting running integral should be interpolated. The default values are 1000 samples and 2nd order interpolation.

The following named arguments are accepted

SupNormSet(const RooArgSet&) – Observables over which should be normalized in_addition to the integration observables ScanParameters(Int_t nbins, – Parameters for scanning technique of making CDF: number Int_t intOrder) of sampled bins and order of interpolation applied on numeric cdf ScanNum() – Apply scanning technique if cdf integral involves numeric integration ScanAll() – Always apply scanning technique ScanNone() – Never apply scanning technique

const RooArgSet normSet,
Double_t  scaleFactor,
Bool_t  correctForBinSize = kFALSE,
Bool_t  showProgress = kFALSE 
) const

Fill a RooDataHist with values sampled from this function at the bin centers.

If extendedMode is true, the p.d.f. values is multiplied by the number of expected events in each bin

An optional scaling by a given scaleFactor can be performed. Returns a pointer to the input RooDataHist, or zero in case of an error.

If correctForBinSize is true the RooDataHist is filled with the functions density (function value times the bin volume) rather than function value.

If showProgress is true a process indicator is printed on stdout in steps of one percent, which is mostly useful for the sampling of expensive functions such as likelihoods

Fill the ROOT histogram 'hist' with values sampled from this function at the bin centers.

Our value is calculated by first integrating out any variables in projectedVars and then scaling the result by scaleFactor. Returns a pointer to the input histogram, or zero in case of an error. The input histogram can be any TH1 subclass, and therefore of arbitrary dimension. Variables are matched with the (x,y,...) dimensions of the input histogram according to the order in which they appear in the input plotVars list. If scaleForDensity is true the histogram is filled with a the functions density rather than the functions value (i.e. the value at the bin center is multiplied with bin volume)

Utility function for createIntObj() that aids in the construct of recursive integrals over functions with multiple observables with parameterized ranges.

This function finds in a given set allObs over which integration is requested the largeset subset of observables that can be integrated simultaneously. This subset consists of observables with fixed ranges and observables with parameterized ranges whose parameterization does not depend on any observable that is also integrated.

Fix the interpretation of the coefficient of any RooAddPdf component in the expression tree headed by this object to the given set of observables.

If the force flag is false, the normalization choice is only fixed for those RooAddPdf components that have the default 'automatic' interpretation of coefficients (i.e. the interpretation is defined by the observables passed to getVal()). If force is true, also RooAddPdf that already have a fixed interpretation are changed to a new fixed interpretation.

Log evaluation error message.

Evaluation errors may be routed through a different protocol than generic RooFit warning message (which go straight through RooMsgService) because evaluation errors can occur in very large numbers in the use of likelihood evaluations. In logEvalError mode, controlled by global method enableEvalErrorLogging() messages reported through this function are not printed but all stored in a list, along with server values at the time of reporting. Error messages logged in this way can be printed in a structured way, eliminating duplicates and with the ability to truncate the list by printEvalErrors. This is the standard mode of error logging during MINUIT operations. If enableEvalErrorLogging() is false, all errors reported through this method are passed for immediate printing through RooMsgService. A string with server names and values is constructed automatically for error logging purposes, unless a custom string with similar information is passed as argument.

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
