)
virtual

Separation Gain: the measure of how the quality of separation of the sample increases by splitting the sample e.g.

into a "left-node" and a "right-node" (N * Index_parent) - (N_left * Index_left) - (N_right * Index_right) this is then the quality crition which is optimized for when trying to increase the information in the system (making the best selection

Reimplemented from TMVA::SeparationBase.

Double_t TMVA::SdivSqrtSplusB::GetSeparationIndex ( const Double_t s,
const Double_t b 
)
virtual

Index = S/sqrt(S+B) (statistical significance)

Implements TMVA::SeparationBase.
