Function documentation

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; }
