Kolmogorov-Smirnov test values

@Einsiedler

I would assume that one could solely rely on their eyes to see if overtraining is significant?

Yes, I think that in many cases this is what it boils down to.

@Einsiedler

However, how can I change the binning?

Unfortunately one has to either

1. do a retraining for this to take effect since a rederivation of the output histograms are beyond the current capabilities of the TMVA::Gui, or
2. manually evaluate the classifier using the TMVA::Reader constructing the histograms manually and finally running the KS test on this.

To change the binning for a retraining use (TMVA::gConfig().GetVariablePlotting()).fNbinsMVAoutput = 300;
at the top of the training file.
