An Implementation of the Bridge Distribution with Logit-Link as
in Wang and Louis (2003)
An implementation of the bridge distribution with logit-link in
R. In Wang and Louis (2003) <10.1093>, such a univariate
bridge distribution was derived as the distribution of the random intercept that
'bridged' a marginal logistic regression and a conditional logistic regression.
The conditional and marginal regression coefficients are a scalar multiple
of each other. Such is not the case if the random intercept distribution was
