Post Hoc tests for interaction in Bayesian repeated-measures ANOVA
I am using JAPS for my analyses, but I have two main elements that appear to be missing in the last version (JASP 0.17.2.1). But perhaps there is another way to do them.
- My first problem is that in non-bayesian repeated-measures ANOVA, the marginal means display some possible interactions, but not all (see print screen). For instance, I have a significant triple interaction category*perspective*PTSD, but it does not appear in the options for the marginal means.
- I wanted to run the same versions of the analyses but with the Bayesian version. However, although in the non-bayesian there is the possibility to compute contrast, this option does not appear in the bayesian version (see print screen attached). I know I can run the Bayesian version of independent sample t-tests and paired sample t-tests to overcome the fact that there is not the contrast option available. However, the issue is that I need to run this analyses with a covariate (Age), which is possible to introduce in the repeated-measure ANOVA (bayesian and frequentist), but this covariate can't be introduce (as far as I know) in the paired and independent sample t-tests.
Would you have solutions for these two points?
Thank you very much!
