Hi @rhazn, are you sure this is to close 45? Maybe that was a typo because 45 deals with ANOVAs and was closed years ago. Please edit the original post to match the relevant Issue if I'm right.

As far as the failing tests, when I make the same single change in L493 as you, I get the same output for all docs/tests as were originally there. Like, it doesn't require the small changes you added. But you passed 3.9 tests (only), so I guess those changes helped with that? I'm not sure fully what the deal is, but just letting you know what I found after a quick check. I'm using Python 3.11 on Windows for what that's worth.

Ah sorry, you are correct. I think I accidentally deleted a number, this PR is in reference to #456.

Sadly, I am not well versed in Python development so I might struggle more with this than average. I am working on OSX, when I run the docs examples with 3.11 in my REPL, I get the following output:

>>> y = np.array([38, 37, 33, 29, 14, 12, 20, 22, 17, 25, 26, 16])
>>> pg.wilcoxon(x, y, alternative='two-sided')

Though with 3.9:

>>> y = np.array([38, 37, 33, 29, 14, 12, 20, 22, 17, 25, 26, 16])

Maybe this is something that is not good to discuss in a PR and should go into a Q&A, but it feels like I am making a mistake with Python venv that is preventing me from providing a good PR 😅 .
