10 * Description: *
11 * Concrete PDEFoam sub-class. This foam stores the discriminant D *
12 * = N_sig / (N_bg + N_sig) with every cell, as well as the *
13 * statistical error on the discriminant. *

2-D histogram with a double per channel (see TH1 documentation)}
Definition: TH2.h:300
This PDEFoam variant stores in every cell the discriminant.
virtual void FillFoamCells(const Event *ev, Float_t wt)
This function fills an event into the discriminant PDEFoam.
virtual void Finalize()
Calc discriminator and its error for every cell and save it to the cell.
virtual TH2D * Project2(Int_t, Int_t, ECellValue, PDEFoamKernelBase *, UInt_t)
Project foam variable idim1 and variable idim2 to histogram.
PDEFoamDiscriminant()
Default constructor for streamer, user should not use it.
This class is the abstract kernel interface for PDEFoam.
