I have the same question as Ricardo.

By stratified, we mean controlling for another covariate:

Wilcoxon of Y by X, controlling for Z

StatXact does this stratified Wilcoxon.

David, the parallel is Mantel-Haenszel for dichotomous outcome.

So, the command would look something like this:

ranksum y x, by(z)


ranksum y, by(x) strata(z)
