class TMVA::MethodBoost: public TMVA::MethodCompositeBase


This class is meant to boost a single classifier. Boosting means
training the classifier a few times. Everytime the wieghts of the
events are modified according to how well the classifier performed
on the test sample.

Double_t GetMvaValue(Double_t* err = 0, Double_t* errUpper = 0)
 return boosted MVA response
Double_t GetBoostROCIntegral(Bool_t , TMVA::Types::ETreeType , Bool_t CalcOverlapIntergral = kFALSE)
 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'

 Calculate MVA values of current method fMethods.back() on
 training sample
void MonitorBoost(TMVA::Types::EBoostStage stage, UInt_t methodIdx = 0)
 fill various monitoring histograms from information of the individual classifiers that
 have been boosted.
 of course.... this depends very much on the individual classifiers, and so far, only for
 Decision Trees, this monitoring is actually implemented
