◆ Density()

Double_t TMVA::PDEFoamDiscriminantDensity::Density ( std::vector< Double_t > &  xev,
Double_t event_density 

This function is needed during the foam buildup.

It returns the average number density of events of type fClass within the range-searching volume (specified by fBox).


  • xev - event vector (in [fXmin,fXmax]) to place the box at
  • event_density - here the event density is stored


Number of events (event weights) of type fClass, which were found in the range-searching volume at point 'xev', divided by the box volume.

Implements TMVA::PDEFoamDensityBase.
