If I try to perform the Chi2Test with two smoothed (calling Th1::Smooth) and weighed histograms the procedure seems stuck forever. This is on ROOT 6.04/02
While it may be questionable to evaluate the chi2 after smoothing, I was wondering if the above behaviour is expected. I could run the K-S test with and without the smoothing in almost the same amount of time.
If you perform smoothing you should not run a Chi2Test, because the bins are correlated. You will not get a statistic meaningful p-valiue. However the program should not be stuck forever.
I can look at this issue if you post a macro reproducing this problems or the two smoothed histograms.
