Dear Andreas,

Thanks for your reply on my question regarding the error of calculating the SE!

I am wondering would the issue of distributional domain also results in the error I asked in another post " [Unable to specify a correct prior distribution](https://discourse.pumas.ai/t/unable-to-specify-a-correct-prior-distribution)"?

I tried to specify priors under both FOCEI and HMC-NUTS, and neither of them could pass the “InverseWishart” prior during the fitting step. I have read the Pumas Bayesian example, it’s using univariate InverseWishart, and my case is multivariate InverseWishart. Could it be an issue?

Thanks!
