Double_t TMVA::MethodBDT::AdaBoost ( std::vector< const TMVA::Event * > &  eventSample,
DecisionTree dt 
)
private

the AdaBoost implementation.

a new training sample is generated by weighting events that are misclassified by the decision tree. The weight applied is w = (1-err)/err or more general: w = ((1-err)/err)^beta where err is the fraction of misclassified events in the tree ( <0.5 assuming demanding the that previous selection was better than random guessing) and "beta" being a free parameter (standard: beta = 1) that modifies the boosting.
