If ttest generalizes to regress, then ranksum generalizes to what?

There is a lot of literature on ranksum tests with clustered data if that's what you mean. Maybe you can define your data more precisely...

Dear all,

Is there a way to adjust the -ranksum- test for covariates? Or is there another way to do an adjusted Mann-Whitney U test? Something similar to relationsip between ttest and regress.

Thank you,
Ricardo.
