Double_t TMVA::MethodBoost::GetBoostROCIntegral ( Bool_t  singleMethod,
Types::ETreeType  eTT,
Bool_t  CalcOverlapIntergral = kFALSE 
)
private

Calculate the ROC integral of a single classifier or even the whole boosted classifier.

The tree type (training or testing sample) is specified by 'eTT'.

If tree type kTraining is set, the original training sample is used to compute the ROC integral (original weights).

  • singleMethod - if kTRUE, return ROC integral of single (last trained) classifier; if kFALSE, return ROC integral of full classifier
  • eTT - tree type (Types::kTraining / Types::kTesting)
  • CalcOverlapIntergral - if kTRUE, the overlap integral of the signal/background MVA distributions is calculated and stored in 'fOverlap_integral'
