◆ GetMulticlassValues()

const std::vector< Float_t > & TMVA::MethodPDEFoam::GetMulticlassValues ( )

virtual

Get the multiclass MVA response for the PDEFoam classifier.

The returned MVA values are normalized, i.e. their sum equals 1.

Reimplemented from TMVA::MethodBase.

Definition at line 792 of file MethodPDEFoam.cxx.

◆ GetMvaValue()

Double_t TMVA::MethodPDEFoam::GetMvaValue	(	Double_t *	err = `0`,
		Double_t *	errUpper = `0`
	)

virtual

Return Mva-Value.

In case of 'fSigBgSeparated==false' (one unifiend PDEFoam was trained) the function returns the content of the cell, which corresponds to the current TMVA::Event, i.e. D = N_sig/(N_bg+N_sig).

In case of 'fSigBgSeparated==true' (two separate PDEFoams were trained) the function returns

D = Density_sig/(Density_sig+Density_bg)

where 'Density_sig' is the content of the cell in the signal PDEFoam (fFoam[0]) and 'Density_bg' is the content of the cell in the background PDEFoam (fFoam[1]).

In both cases the error on the discriminant is stored in 'err' and 'errUpper'. (Of course err and errUpper must be non-zero and point to valid address to make this work.)

Implements TMVA::MethodBase.
