    Details

      Description

      The p value obtained when using TH1::KolmogorovTest with the option "X", are biased to lower values.  

      The reason is that when generating pseudo-experiments only one of  the histogram is randomized. 

      This affects the p-values that are displayed in the TMVAGui
