	)

Constructor from a RooDataHist.

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.

Constructor from a RooDataHist.

The first list of observables are the p.d.f. observables, which may any RooAbsReal (function or variable). The second list are the corresponding observables in the RooDataHist which must be of type RooRealVar or RooCategory This constructor thus allows to apply a coordinate transformation on the histogram data to be applied.

selfNormalized()

bool RooHistPdf::selfNormalized ( ) const

inlineoverridevirtual

Shows if a PDF is self-normalized, which means that no attempt is made to add a normalization term.

Always returns false, unless a PDF overrides this function.
