Class Description

PDF( const TH1 *hist, TMVA::PDF::SmoothMethod method, Int_t nsmooth )
 constructor:
 - default Spline method is: Spline2 (quadratic)
 - default smoothing is none
~PDF( void )
 destructor
void FillSplineToHist( void )
 creates high-binned reference histogram to be used in stead of the
 PDF for speed reasons
void CheckHist(void)
 sanity check: compare PDF with original histogram
Double_t Integral( void )
 computes normalisation
Double_t GetIntegral( Double_t xmin, Double_t xmax )
 computes PDF integral within given ranges
Double_t GetVal( const Double_t x )
 returns value PDF(x)
PDF( const TH1* theHist, PDF::SmoothMethod method = kSpline2, Int_t nsmooth = 0 )


TSpline* GetSpline( void )
