Bayesian linear mixed model default prior
Hello! I was wondering what the default prior is in JASP for Bayesian linear mixed models. I noticed that there are no options to change the prior specification, so I was hoping to understand the exact distribution(s) being used. I believe it is the same as the rstanarm, but it would be helpful to include this information in the blue "i" icon!
Best,
KC

Hi KC,
Yes, the Bayesian (Generalized) Mixed Models analysis uses the autoscaled priors from rstanarm (as the analysis provides estimation only and no Bayes factors). We should've described this better in the documentation -- we are planning to make the prior specification accessible to the users. (We will update the documentation accordingly.)
Cheers,
Frantisek
