    Description

      Current Chi-Square test implementation only supports standard Chi-Square testing with respect to known distribution. We needed testing for comparison of two sample data sets where the distribution can be unknown. For this case the Chi-Square test has to be computed in a different way so that both error contributions (one for each sample data set) are taken into account. See Press et. al, Numerical Recipes, Second Edition, formula 14.3.2.
