Function documentation

PDF(const TString& name, Bool_t norm = kTRUE)

 default constructor needed for ROOT I/O

PDF(const TString& name, const TH1* theHist, TMVA::PDF::EInterpolateMethod method = kSpline2, Int_t minnsmooth = 0, Int_t maxnsmooth = 0, Bool_t checkHist = kFALSE, Bool_t norm = kTRUE)

 constructor of spline based PDF:

PDF(const TString& name, const TH1* theHist, TMVA::KDEKernel::EKernelType ktype, TMVA::KDEKernel::EKernelIter kiter, TMVA::KDEKernel::EKernelBorder kborder, Float_t FineFactor, Bool_t norm = kTRUE)

 constructor of kernel based PDF:

PDF(const TString& name, const TString& options, const TString& suffix = "", TMVA::PDF* defaultPDF = 0, Bool_t norm = kTRUE)

~PDF()

 destructor

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()

 Simple conversion

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)

 computes PDF integral within given ranges

Double_t GetVal(Double_t x) const

 returns value PDF(x)

Double_t GetValInverse(Double_t y, Bool_t isMonotonouslyIncreasingFunction = kFALSE) const

 returns value PDF^{-1}(y)

void FindBinInverse(const TH1* histogram, Int_t& lowerBin, Int_t& higherBin, Double_t& lowerBinValue, Double_t& higherBinValue, Double_t y, Bool_t isMonotonouslyIncreasingFunction = kFALSE) const

 find bin from value on ordinate

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)

void ProcessOptions()

void AddXMLTo(void* parent)

PDF*& GetThisPdfThreadLocal()

 static pointer to this object
 This is a workaround for OSx where static thread_local data members are
 not supported. The C++ solution would indeed be the following:

{ TTHREAD_TLS(PDF*) fgThisPDF(nullptr); return fgThisPDF; }
