Hm. I was following tutorial and found these lines

Quote:


...

theAnalysis->FillList( looseElectrons, "ElectronLoose", "PidAlgoEmcBayes;PidAlgoDrc;PidAlgoMvd");

In this case the probabilities for PID selection are achieved by multiplying the probability values of the chosen algorithms, i.e. Pe = Pe,1 × Pe,2 × Pe,3, etc.



The only case one can get increase in efficiency is if one of the probabilities >1 what is impossible. Am I right?
