I’m using TMVA Root on several samples (Signal vs Backgrounds). In inputs, I specified a weight for every background for the training to make my sample statistics fit with the reality. But, I also applied some cuts for the training in the PrepareTrainingAndTestTree method. Then these cuts affect the statistic of my samples. My question is : Does TMVA take into account the cuts and modify the existing weights to keep the same kind of statistic before the cuts ?
