PDEFoamDistr()

{}

~PDEFoamDistr()

PDEFoamDistr(const TMVA::PDEFoamDistr& )

 Copy constructor

void Initialize(Int_t ndim = 2)

 Initialisation procedure of internal foam density.
 Set dimension to 'ndim' and create BinarySearchTree.

void SetDim(Int_t idim)

 set dimension of distribution

void FillBinarySearchTree(const TMVA::Event* ev, TMVA::EFoamType ft, Bool_t NoNegWeights = kFALSE)

 This method creates an TMVA::Event and inserts it into the
 binary search tree.

 If 'NoNegWeights' is true, an event with negative weight will
 not be filled into the foam.  (Default value: false)

Double_t Density(Double_t* Xarg, Double_t& event_density)

 This function is needed during the foam buildup.
 It return a certain density depending on the selected classification
 or regression options:

 In case of separated foams (classification) or multi target regression:
  - returns event density within volume (specified by VolFrac)
 In case of unified foams: (classification)
  - returns discriminator (N_sig)/(N_sig + N_bg) divided by volume
    (specified by VolFrac)
 In case of mono target regression:
  - returns average target value within volume divided by volume
    (specified by VolFrac)

void SetVolumeFraction(Float_t vfr)

 Getter and setter for VolFrac option

{fVolFrac=vfr; return;}

Float_t GetVolumeFraction()

{return fVolFrac;}

void SetXmin(Int_t idim, Float_t wmin)

 set foam boundaries

{fXmin[idim]=wmin; return;}

void SetXmax(Int_t idim, Float_t wmax)

{fXmax[idim]=wmax; return;}

Float_t VarTransform(Int_t idim, Float_t x)

 transformation functions for event variable into foam boundaries
 reason: foam allways has boundaries [0, 1]

Float_t VarTransformInvers(Int_t idim, Float_t x)

void SetDensityCalc(TMVA::TDensityCalc dc)

 Getters and setters for foam filling method

{ fDensityCalc = dc; }

Bool_t FillDiscriminator()

{ return fDensityCalc == kDISCRIMINATOR; }

Bool_t FillTarget0()

{ return fDensityCalc == kTARGET; }

Bool_t FillEventDensity()

{ return fDensityCalc == kEVENT_DENSITY; }

void SetSignalClass(Int_t cls)

{ fSignalClass = cls; }

void SetBackgroundClass(Int_t cls)

{ fBackgroundClass = cls; }
