Class Description

RooHistPdf(const char *name, const char *title, const RooArgSet& vars, const RooDataHist& dhist, Int_t intOrder)
 Constructor from a RooDataHist. The variable listed in 'vars' control the dimensionality of the
 PDF. Any additional dimensions present in 'dhist' will be projected out. RooDataHist dimensions
 can be either real or discrete. See RooDataHist::RooDataHist for details on the binning.
 RooHistPdf neither owns or clone 'dhist' and the user must ensure the input histogram exists
 for the entire life span of this PDF.
RooHistPdf(const RooHistPdf& other, const char* name)
 Copy constructor
Double_t evaluate()
 Return the current value: The value of the bin enclosing the current coordinates
 of the dependents, normalized by the histograms contents
Int_t getAnalyticalIntegral(RooArgSet& allVars, RooArgSet& analVars, const char* rangeName)
 Determine integration scenario. RooHistPdf can perform all integrals over
 its dependents analytically via partial or complete summation of the input histogram.
