Bayesian Logistic Regression
The Observational Medical Outcomes Partnership (OMOP) of the Foundation for the National Institute of Health (FNIH) researches methods for analysis of healthcare databases. One of their methods is "Bayesian Logistic Regression"
Here is their description of the method:
The blue box is a dichotomous Facets-type Rasch model with n+1 facets. n facets have two elements 0 and 1. The B0 facet has one element, non-centered.
The Red box is an artificial centralizing bias on the element measures. They could obtain a similar effect by using dummy weighted data in Facets.

Example: with 2 covariates, x1, x2
