Function documentation

PDF()
 default constructor needed for ROOT I/O
PDF(const TH1* theHist, TMVA::PDF::EInterpolateMethod method = kSpline2, Int_t nsmooth = 0, Bool_t checkHist = kFALSE)
 constructor of spline based PDF:
 - default Spline method is: Spline2 (quadratic)
 - default smoothing is none
PDF(const TH1* theHist, TMVA::KDEKernel::EKernelType ktype, TMVA::KDEKernel::EKernelIter kiter, TMVA::KDEKernel::EKernelBorder kborder, Float_t FineFactor)
 constructor of kernel based PDF:
 - default kernel type is Gaussian
 - default number of iterations is 1 (i.e. nonadaptive KDE)
 sanity check
~PDF()
 destructor
void BuildPDF(Bool_t checkHist = kFALSE)
 build the PDF from the original histograms
void FillKDEToHist()
 creates high-binned reference histogram to be used instead of the
 PDF for speed reasons
void FillSplineToHist()
 creates high-binned reference histogram to be used instead of the
 PDF for speed reasons
void CheckHist()
 sanity check: compare PDF with original histogram
void ValidatePDF(TH1* original = 0) const
 comparison of original histogram with reference PDF
Double_t GetIntegral()
 computes normalisation
Double_t IGetVal(Double_t* , Double_t* )
 static external auxiliary function (integrand)
Double_t GetIntegral(Double_t xmin, Double_t xmax)
 computes PDF integral within given ranges
Double_t GetVal(Double_t x) const
 returns value PDF(x)
TH1* GetPDFHist()
