◆ GetROCIntegral()

Double_t TMVA::OptimizeConfigParameters::GetROCIntegral ( )

private

calculate the area (integral) under the ROC curve as a overall quality measure of the classification

making pdfs out of the MVA-output distributions doesn't work reliably for cases where the MVA-output isn't a smooth distribution. this happens "frequently" in BDTs for example when the number of trees is small resulting in only some discrete possible MVA output values. (I still leave the code here, but use this with care!!! The default however is to use the distributions!!!
