 constructor of spline based PDF:
PDF( const TString& name, const TH1* hist, KDEKernel::EKernelType ktype, KDEKernel::EKernelIter kiter, KDEKernel::EKernelBorder kborder, Float_t FineFactor, Bool_t norm)
 constructor of kernel based PDF:
PDF(const TString& name, const TString& options, const TString& suffix = "", TMVA::PDF* defaultPDF = 0, Bool_t norm = kTRUE)
void BuildPDF(const TH1* theHist)
Int_t GetHistNBins(Int_t evtNum = 0)
void BuildSplinePDF()
 build the PDF from the original histograms
void BuildKDEPDF()
 creates high-binned reference histogram to be used instead of the
 PDF for speed reasons
void SmoothHistogram()
void FillHistToGraph()
void FillSplineToHist()
 creates high-binned reference histogram to be used instead of the
 PDF for speed reasons
void CheckHist() const
 sanity check: compare PDF with original histogram
void ValidatePDF(TH1* original = 0) const
 comparison of original histogram with reference PDF
Double_t GetIntegral() const
 computes normalisation
Double_t IGetVal(Double_t* , Double_t* )
 static external auxiliary function (integrand)
Double_t GetIntegral(Double_t xmin, Double_t xmax)

 returns value PDF(x)
void DeclareOptions()
 define the options (their key words) that can be set in the option string
 know options:
 PDFInterpol[ivar] <string>   Spline0, Spline1, Spline2 <default>, Spline3, Spline5, KDE  used to interpolate reference histograms
             if no variable index is given, it is valid for ALL the variables

 NSmooth           <int>    how often the input histos are smoothed
 MinNSmooth        <int>    min number of smoothing iterations, for bins with most data
 MaxNSmooth        <int>    max number of smoothing iterations, for bins with least data
 NAvEvtPerBin      <int>    minimum average number of events per PDF bin
 TransformOutput   <bool>   transform (often strongly peaked) likelihood output through sigmoid inversion
 fKDEtype          <KernelType>   type of the Kernel to use (1 is Gaussian)
 fKDEiter          <KerneIter>    number of iterations (1 --> "static KDE", 2 --> "adaptive KDE")
 fBorderMethod     <KernelBorder> the method to take care about "border" effects (1=no treatment , 2=kernel renormalization, 3=sample mirroring)
