Conover's post hoc references
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?
