I am running a regression with a negative binomial error. The outcome is occasionally censored from below, but I am getting the following error on the line with the neg_binomial_2_lcdf call: Exception: grad_2F1: k (internal counter) exceeded 100000 iterations, hypergeometric function gradient did …

`neg_binomial_2_lcdf()` "grad_2F1: k (internal counter) exceeded 100000 iterations"

That shouldn’t be crashing a chain, this is good to know. I’ll check what is…
