class RooAbsReal: public RooAbsArg



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.

RooAbsReal* createProfile(const RooArgSet& paramsOfInterest)
 Create a RooProfileLL object that eliminates all nuisance parameters in the
 present function. The nuisance parameters are defined as all parameters
 of the function except the stated paramsOfInterest
RooAbsReal* createIntegral(const RooArgSet& iset, const RooCmdArg& arg1, const RooCmdArg& arg2 = RooCmdArg::none(), const RooCmdArg& arg3 = RooCmdArg::none(), const RooCmdArg& arg4 = RooCmdArg::none(), const RooCmdArg& arg5 = RooCmdArg::none(), const RooCmdArg& arg6 = RooCmdArg::none(), const RooCmdArg& arg7 = RooCmdArg::none(), const RooCmdArg& arg8 = RooCmdArg::none()) const
 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

 The following named arguments are accepted

 NormSet(const RooArgSet&)            -- Specify normalization set, mostly useful when working with PDFS
 NumIntConfig(const RooNumIntConfig&) -- Use given configuration for any numeric integration, if necessary
 Range(const char* name)              -- Integrate only over given range. Multiple ranges may be specified
                                         by passing multiple Range() arguments
RooAbsReal* createIntegral(const RooArgSet& iset, const RooArgSet* nset = 0, const RooNumIntConfig* cfg = 0, const char* rangeName = 0) const
 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
RooAbsReal* createIntObj(const RooArgSet& iset, const RooArgSet* nset, const RooNumIntConfig* cfg, const char* rangeName) const
 Utility function for createIntegral that creates the actual integreal object
void findInnerMostIntegration(const RooArgSet& allObs, RooArgSet& innerObs, const char* rangeName) const
 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.
TString integralNameSuffix(const RooArgSet& iset, const RooArgSet* nset = 0, const char* rangeName = 0, Bool_t omitEmpty = kFALSE) const
 Construct string with unique suffix name to give to integral object that encodes
 integrated observables, normalization observables and the integration range name
const RooAbsReal* createPlotProjection(const RooArgSet& depVars, const RooArgSet& projVars, RooArgSet*& cloneSet) const
 Utility function for plotOn() that creates a projection of a function or p.d.f
 to be plotted on a RooPlot.
const RooAbsReal* createPlotProjection(const RooArgSet& depVars, const RooArgSet& projVars) const
 Utility function for plotOn() that creates a projection of a function or p.d.f
 to be plotted on a RooPlot.
const RooAbsReal * createPlotProjection(const RooArgSet& dependentVars, const RooArgSet* projectedVars, RooArgSet*& cloneSet, const char* rangeName = 0, const RooArgSet* condObs = 0) const
 Utility function for plotOn() that creates a projection of a function or p.d.f
 to be plotted on a RooPlot.

 Create a new object G that represents the normalized projection:

             Integral [ F[x,y,p] , { y } ]
  G[x,p] = ---------------------------------
            Integral [ F[x,y,p] , { x,y } ]

 where F[x,y,p] is the function we represent, "x" are the
 specified dependentVars, "y" are the specified projectedVars, and
 "p" are our remaining variables ("parameters"). Return a
 pointer to the newly created object, or else zero in case of an
 error.  The caller is responsible for deleting the contents of
 cloneSet (which includes the returned projection object)
TH1 * fillHistogram(TH1* hist, const RooArgList& plotVars, Double_t scaleFactor = 1, const RooArgSet* projectedVars = 0, Bool_t scaling = kTRUE, const RooArgSet* condObs = 0, Bool_t setError = kTRUE) const
 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)
RooDataHist* fillDataHist(RooDataHist* hist, const RooArgSet* nset, Double_t scaleFactor, Bool_t correctForBinVolume = 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
TH1* createHistogram(const char* varNameList, Int_t xbins = 0, Int_t ybins = 0, Int_t zbins = 0) const
 Create and fill a ROOT histogram TH1,TH2 or TH3 with the values of this function for the variables with given names
 The number of bins can be controlled using the [xyz]bins parameters. For a greater degree of control
 use the createHistogram() method below with named arguments

 The caller takes ownership of the returned histogram
TH1 * createHistogram(const char* name, const RooAbsRealLValue& xvar, const RooCmdArg& arg1 = RooCmdArg::none(), const RooCmdArg& arg2 = RooCmdArg::none(), const RooCmdArg& arg3 = RooCmdArg::none(), const RooCmdArg& arg4 = RooCmdArg::none(), const RooCmdArg& arg5 = RooCmdArg::none(), const RooCmdArg& arg6 = RooCmdArg::none(), const RooCmdArg& arg7 = RooCmdArg::none(), const RooCmdArg& arg8 = RooCmdArg::none()) const
 Create and fill a ROOT histogram TH1,TH2 or TH3 with the values of this function.

 This function accepts the following arguments

 name -- Name of the ROOT histogram
 xvar -- Observable to be mapped on x axis of ROOT histogram

 IntrinsicBinning()                           -- Apply binning defined by function or pdf (as advertised via binBoundaries() method)
 Binning(const char* name)                    -- Apply binning with given name to x axis of histogram
 Binning(RooAbsBinning& binning)              -- Apply specified binning to x axis of histogram
 Binning(int nbins, [double lo, double hi])   -- Apply specified binning to x axis of histogram
 ConditionalObservables(const RooArgSet& set) -- Do not normalized PDF over following observables when projecting PDF into histogram
 Scaling(Bool_t)                              -- Apply density-correction scaling (multiply by bin volume), default is kTRUE
 Extended(Bool_t)                             -- Plot event yield instead of probability density (for extended pdfs only)

 YVar(const RooAbsRealLValue& var,...)    -- Observable to be mapped on y axis of ROOT histogram
 ZVar(const RooAbsRealLValue& var,...)    -- Observable to be mapped on z axis of ROOT histogram

 The YVar() and ZVar() arguments can be supplied with optional Binning() arguments to control the binning of the Y and Z axes, e.g.
 createHistogram("histo",x,Binning(-1,1,20), YVar(y,Binning(-1,1,30)), ZVar(z,Binning("zbinning")))

 The caller takes ownership of the returned histogram
TH1* createHistogram(const char* name, const RooAbsRealLValue& xvar, RooLinkedList& argList) const
 Internal method implementing createHistogram
void plotOnCompSelect(RooArgSet* selNodes) const
 Helper function for plotting of composite p.d.fs. Given
 a set of selected components that should be plotted,
 find all nodes that (in)directly depend on these selected
 nodes. Mark all directly and indirecty selected nodes
 as 'selected' using the selectComp() method
RooPlot* plotOn(RooPlot* frame, const RooCmdArg& arg1 = RooCmdArg(), const RooCmdArg& arg2 = RooCmdArg(), const RooCmdArg& arg3 = RooCmdArg(), const RooCmdArg& arg4 = RooCmdArg(), const RooCmdArg& arg5 = RooCmdArg(), const RooCmdArg& arg6 = RooCmdArg(), const RooCmdArg& arg7 = RooCmdArg(), const RooCmdArg& arg8 = RooCmdArg(), const RooCmdArg& arg9 = RooCmdArg(), const RooCmdArg& arg10 = RooCmdArg()) const
 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)

 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
RooPlot* plotOn(RooPlot* frame, RooLinkedList& cmdList) const
 Internal back-end function of plotOn() with named arguments
RooPlot* plotOn(RooPlot* frame, RooAbsReal::PlotOpt o) const
 Plotting engine function for internal use

 Plot ourselves on given frame. If frame contains a histogram, all dimensions of the plotted
 function that occur in the previously plotted dataset are projected via partial integration,
 otherwise no projections are performed. Optionally, certain projections can be performed
 by summing over the values present in a provided dataset ('projData'), to correctly
 project out data dependents that are not properly described by the PDF (e.g. per-event errors).

 The functions value can be multiplied with an optional scale factor. The interpretation
 of the scale factor is unique for generic real functions, for PDFs there are various interpretations
 possible, which can be selection with 'stype' (see RooAbsPdf::plotOn() for details).

 The default projection behaviour can be overriden by supplying an optional set of dependents
 to project. For most cases, plotSliceOn() and plotProjOn() provide a more intuitive interface
 to modify the default projection behavour.
RooPlot* plotSliceOn(RooPlot* frame, const RooArgSet& sliceSet, Option_t* drawOptions = "L", Double_t scaleFactor = 1., RooAbsReal::ScaleType stype = Relative, const RooAbsData* projData = 0) const

RooPlot* plotAsymOn(RooPlot* frame, const RooAbsCategoryLValue& asymCat, RooAbsReal::PlotOpt o) const

 Plot asymmetry of ourselves, defined as

   asym = f(asymCat=-1) - f(asymCat=+1) / ( f(asymCat=-1) + f(asymCat=+1) )

 on frame. If frame contains a histogram, all dimensions of the plotted
 asymmetry function that occur in the previously plotted dataset are projected via partial integration.
 Otherwise no projections are performed,

 The asymmetry function can be multiplied with an optional scale factor. The default projection
 behaviour can be overriden by supplying an optional set of dependents to project.
Double_t getPropagatedError(const RooFitResult& fr)
 Calculate error on self by propagated errors on parameters with correlations as given by fit result
 The linearly propagated error is calculated as follows
                                    T
 error(x) = 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) this function and 'da' taken from the fit result
       Corr(a,a') = the correlation matrix from the fit result

RooPlot* plotOnWithErrorBand(RooPlot* frame, const RooFitResult& fr, Double_t Z, const RooArgSet* params, const RooLinkedList& argList, Bool_t method1) const
 Plot function or p.d.f. on frame with support for visualization of the uncertainty encoded in the given fit result fr.
 If params is non-zero, only the subset of the parameters in fr that occur in params is considered for the error evaluation
 Argument argList can contain any RooCmdArg named argument that can be applied to a regular plotOn() operation

 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 signifance 'Z sigma band'

 The linear method is fast (required 2*N evaluations of the curve, where N is the number of parameters), but may

 Intervals from the sampling method can be asymmetric, and may perform better in the presence of strong correlations

 (in arbitrary order). For example, calling bindVars({x1,x3}) on an object
 F(x1,x2,x3,x4) returns an object f(x1,x3) that is evaluated using the
 current values of x2 and x4. The caller takes ownership of the returned adaptor.
void copyCache(const RooAbsArg* source, Bool_t valueOnly = kFALSE, Bool_t setValDirty = kTRUE)

 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.

void logEvalError(const RooAbsReal* originator, const char* origName, const char* message, const char* serverValueString = 0)
 Interface to insert remote error logging messages received by RooRealMPFE into current error loggin stream
void logEvalError(const char* message, const char* serverValueString = 0) const
 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.
void clearEvalErrorLog()

void fixAddCoefNormalization(const RooArgSet& addNormSet = RooArgSet(), Bool_t force = kTRUE)
 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.
void fixAddCoefRange(const char* rangeName = 0, Bool_t force = kTRUE)
 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 range choice is only fixed for those
 RooAddPdf components that currently use the default full domain to interpret their
 coefficients. If force is true, also RooAddPdf that already have a fixed
 interpretation range are changed to a new fixed interpretation range.
void preferredObservableScanOrder(const RooArgSet& obs, RooArgSet& orderedObs) const
 Interface method for function objects to indicate their prefferred order of observables
 for scanning their values into a (multi-dimensional) histogram or RooDataSet. The observables
 to be ordered are offered in argument 'obs' and should be copied in their preferred
 order into argument 'orderdObs', This default implementation indicates no preference
 and copies the original order of 'obs' into 'orderedObs'
RooAbsReal* createRunningIntegral(const RooArgSet& iset, const RooArgSet& nset = RooArgSet())
 Create a running integral over this function, i.e. given a f(x), create an object
 representing 'int[x_lo,x] f(x_prime) dx_prime'
RooAbsReal* createRunningIntegral(const RooArgSet& iset, const RooCmdArg& arg1, const RooCmdArg& arg2 = RooCmdArg::none(), const RooCmdArg& arg3 = RooCmdArg::none(), const RooCmdArg& arg4 = RooCmdArg::none(), const RooCmdArg& arg5 = RooCmdArg::none(), const RooCmdArg& arg6 = RooCmdArg::none(), const RooCmdArg& arg7 = RooCmdArg::none(), 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

                                   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.
RooFitResult* chi2FitTo(RooDataSet& xydata, const RooLinkedList& cmdList)
 Internal back-end function to steer chi2 fits
RooAbsReal* createChi2(RooDataSet& data, const RooCmdArg& arg1 = RooCmdArg::none(), const RooCmdArg& arg2 = RooCmdArg::none(), const RooCmdArg& arg3 = RooCmdArg::none(), const RooCmdArg& arg4 = RooCmdArg::none(), const RooCmdArg& arg5 = RooCmdArg::none(), const RooCmdArg& arg6 = RooCmdArg::none(), const RooCmdArg& arg7 = RooCmdArg::none(), const RooCmdArg& arg8 = RooCmdArg::none())
 Create a chi-2 from a series of x and y value stored in a dataset.
 The y values can either be the event weights (default), or can be another column designated
 by the YVar() argument. The y value must have errors defined for the chi-2 to
 be well defined.

 The following named arguments are supported

 Options to control construction of the chi^2

 YVar(RooRealVar& yvar)          -- Designate given column in dataset as Y value
 Integrate(Bool_t flag)          -- Integrate function over range specified by X errors
                                    rather than take value at bin center.
