Conover's post hoc references
Hello,
Jasp uses Conover's post hoc in repeated measures ANOVA for nonparametric data.
I am looking for references to his work to cite in my research, but the only one I found was a 1980 book (2nd edition), Practical Nonparametric Statistics, where he talks about the subject. I did not get this book, so I do not know if it's the true bibliographic reference for what is used in Jasp.
Can someone help me?

The book can be found at https://nl1lib.org/. I'll forward this issue to our ANOVA expert. We ought to mention something about this in the help file...
Cheers,
E.J.
Hi @gutenbar,
The Conover test is a pairwise test that compares the average ranks between two groups (these are giving by JASP as Wi and Wj; see also the help file, under Output -> Nonparametrics). The relevant reference here is
Unfortunately it's a relatively obscure test, so more references are not available.
Kind regards,
Johnny
Thank you @EJ and @JohnnyB .
Just for curiosity: do you know why, as a relatively obscure test, it was the chosen one to be used in Jasp?
It is the proper follow-up test for Friedman's test because it's pairwise and rank-based, while still taking into account all observations (i.e., it uses the aggregated ranking from all observations).
