Hello everybody, I am fitting a multiple outcome mixed effects model where the correlation between the outcomes are going to capture by the random effects (random intercept). The random intercept follows N~(0,sigma_u) I am having a hard time of selecting an appropriate prior for the sigma_u. I …

As Erling said, your priors are likely causing a lot of problems here. With the function inv_logit(x), as soon as x gets larger than ~19, the function will only return 1. So you should look at making those priors significantly smaller. Additionally, you should try the non-centered parameterisation …

Looking for some advice based the n_eff and the pairs plot for mixed effects models

Welcome!

Over here Reparameterizing to avoid low E-BFMI warning this might give you some pointers.
