Hi, I trying to implement non-centered paramatrization to a model I’m working on. I have an issue with setting the lower bound for a vector variable (the issue being that the constraining variable is also a vector). Original, centered model snippet looks like this: parameters{ // Hyperparameter …

[image] SpTB: Additionally, if this proves to be impossible: is it a reasonable practice to non-center some parameters and leave others centered? Hi, For this case, see the discussion in Partial non-centered parametrizations in Stan
