Phil Steitz reopened MATH-160:
------------------------------
Good catch, Luc. I thought clirr was set up to fail the build when this
happens. In any case, this needs to be fixed somehow. Probably best to use a
separate interface.
> Chi-Square Test for Comparing two binned Data Sets

>
> 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.
