class TMVA::PDEFoamDiscriminant: public TMVA::PDEFoam


 PDEFoamDiscriminant

 This PDEFoam variant stores in every cell the discriminant

    D = #events with given class / total number of events

 as well as the statistical error on the discriminant.  It therefore
 acts as a discriminant estimator.  It should be booked together
 with the PDEFoamDiscriminantDensity density estimator, which
 returns the discriminant density at a given phase space point
 during the foam build-up.

Function documentation

PDEFoamDiscriminant()
 Default constructor for streamer, user should not use it.
PDEFoamDiscriminant(const TString& , UInt_t )
{}
PDEFoamDiscriminant(const TMVA::PDEFoamDiscriminant& )
 Copy Constructor  NOT IMPLEMENTED (NEVER USED)
void FillFoamCells(const TMVA::Event* ev, Float_t wt)
 This function fills an event into the discriminant PDEFoam.  The
 event weight 'wt' is filled into cell element 0 if the event is
 of class fClass, and filled into cell element 1 otherwise.
void Finalize()
 Calc discriminator and its error for every cell and save it to
 the cell.
TH2D* Project2(Int_t , Int_t , TMVA::ECellValue , TMVA::PDEFoamKernelBase* , UInt_t )
 Project foam variable idim1 and variable idim2 to histogram.
 The projection algorithm is modified such that the z axis range
 of the returned histogram is [0, 1], as necessary for the
 interpretation as a discriminator.  This is done by weighting
 the cell values (in case of cell_value = kValue) by the cell
 volume in all dimensions, excluding 'idim1' and 'idim2'.

 Parameters:

 - idim1, idim2 - dimensions to project to

 - cell_value - the cell value to draw

 - kernel - a PDEFoam kernel (optional).  If NULL is given, the
            kernel is ignored and the pure cell values are
            plotted.

 - nbin - number of bins in x and y direction of result histogram
          (optional, default is 50).

 Returns:
 a 2-dimensional histogram
