I previously asked about improving model sampling speed fitting about 14K observations to about 200 groups. I am fitting a hierarchical model with Negative Binomial(alpha, mu) distributed likelihood (observations underneath level_2). The priors for the parameters alpha and mu (level_2) are Gamma(hy…
