Title: An Implementation of the Bridge Distribution with Logit-Link as in Wang and Louis (2003)

Description: An implementation of the bridge distribution with logit-link in R. In Wang and Louis (2003), such a bridge distribution was derived as the distribution of the random intercept that facilitated having a conditional logistic regression that when marginalized by integrating out the random intercept left a marginal logistic regression, and the conditional and marginal regression coefficients are a scalar multiple of each other.
