RooChi2MCSModule is an add-on module to RooMCStudy that calculates the chi-squared of fitted p.d.f with respect to a binned version of the data.

For each fit the chi-squared, the reduced chi-squared the number of degrees of freedom and the probability of the chi-squared is store in the summary dataset.
