Hi,
When I run Mann Whitney U test, results are not matched with the results from
other statistical softwares. Besides, I tried to use Kruskal-Wallis test for 2
group, and Kruskal-Wallis results are matched with the results of other
statistical softwares.
I realized that this error occurs with stable versions and nightly builds.
I use Kruskal-Wallis for two groups instead of Mann Whitney U test for now.
But it comes with practical issues (e.g. when I try to compare group 1 and
group 3, I have to recode groups to different variable, because K-W includes
group 2 too.)
