Weights in TMVAClassificationApplication

TMVA
1

hello everybody,

I want to analyze a MC sample with TMVAClassificationApplication. I have already trained and tested the methods using discrete samples (with weighted events) for signal and background . So I want to analyze a composite sample (containing signal and background), but I cannot find how to deal with the weight of the events. Is it possible to use weighted events in TMVAClassificationApplication?

thanks in advance!

Hi ,

I am not sure what exactly is your problem. You can just apply the event weight on the given output obtained by the classifier. Is this not correct for you ?
