Hi
Apologies for my naive question, since I am quite new to TMVA;
Suppose I am having the MET as variable, and I assign the trees like
factory->AddSignalTree ( signal, signalWeight );
factory->AddBackgroundTree( background, backgroundWeight );
would it be possible to also somehow get an mva output from real data collection, ie a histo that contains MET from real data?
In other words, from mva I get signal+bkg response from MC, but what about data ? How can I do it ?
thanks
Alex
