Hi @linas! The model that I posted ([zoib.stan](https://canada1.discourse-cdn.com/flex030/uploads/mc_stan/original/2X/4/4f6280c0fe2b6cfca42688494e427559ff4c32b1.stan)) also has \mu varying for each observation.

If that doesn’t solve your problem, could you please clarify what your intended model is (e.g., using math notation), so we can get a better sense for whether your Stan model matches your intended model?
