I continue building a weighted version of the Mann–Whitney \(U\) test. While previously suggested approach feel promising, I don’t like the usage of Bootstrap to obtain the \(p\)-value. It is always better to have a deterministic and exact approach where it’s possible. I still don’t know how to solve it in general case, but it seems that I’ve obtained a reasonable solution for some specific cases. The current version of the approach still has issues and requires additional correction factors in ...
