The following question is one of those holy grails for me for some time now, I hope someone might be able to offer a good advice.
I wish to perform a non-parametric repeated measures multiway anova using R.
I have been doing some online searching and reading for some time, and so far was able to find solutions for only some of the cases: friedman test for one way nonparametric repeated measures anova, ordinal regression with {car} Anova function for multi way nonparametric anova, and so on. The partial solutions is NOT what I am looking for in this question thread. I have summarized my findings so far in a post I published some time ago (titled: Repeated measures ANOVA with R (functions and tutorials), in case it would help anyone)
If what I read online is true, this task might be achieved using a mixed Ordinal Regression model (a.k.a: Proportional Odds Model).
I found two packages that seems relevant, but couldn't find any vignette on the subject:
So being new to the subject matter, I was hoping for some directions from people here.
Are there any tutorials/suggested-reading on the subject? Even better, can someone suggest a simple example code for how to run and analyse this in R (e.g: "non-parametric repeated measures multiway anova") ?
