The short answer is a bayesian hierarchical model. See this paper from political analysis http://www.carlislerainey.com/papers/separation.pdf On Thu, Jul 26, 2018, 9:33 AM C. AMAL D. GLELE <altessedac2 at gmail.com> wrote:

Check out the blme package. You can specify priors for fixed effects; this is one way of handling the complete separation problem. For choice of prior, Greenland and Mansournia ( https://www.ncbi.nlm.nih.gov/pubmed/26011599) suggest using log-F(1, 1) over other common suggestions like normal, or Jeffrey's or t-priors. But blme provides a quick solution that limits you to normal or t. On Thu, 26 Jul 2018 at 09:33, C. AMAL D. GLELE <altessedac2 at gmail.com> wrote:
