WebJan 24, 2024 · Hi Paul, Thank you again for brms. It has been great. I notice that it doesn't currently support truncation and censoring at the same time. Although it is easy to add - FUN_lccdf(trunc(i), ...) into the stan code generated from make_stancode, I think it might be helpful to allow truncation in the main brms formula.
