Hi Stephen: I think you can use the Kolmogorov Smirnov statistics, it compares the vertical distances between two empirical distributions so you can use it for deciding whether they have the same distribution or one is bigger than the other. About the Wald-Wolfowitz statistic I can't tell you anything. Marķa Elena.

My problem concerns comparing whether two empirical frequency distributions are significantly different. The distributions are based on a full dataset and a subset of that dataset (cut-down data set) so they do not represent

independent samples. I am aware of the various tests for comparing distributions (Chi-Square, Kolm-Smirnov, Wald-Wolfowitz) but I am not sure which, if any, are appropriate for this scenario.

Does anyone have any comments on the appropriate test in this case?

Thanks in advance
