Webbridge 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 Gaussian. Depends R (>= 3.0.0) Web1.3. Contribution In the paper, we consider consistent additive and reverse models under two distributions of the random terms: i.i.d. EV, i.e. Logit, and multivariate normal, i.e. Probit. In the theoretical part of the paper, we address two issues. The ﬁrst is the derivation of probabilities for best, worst and best–worst choices. rcs.org periodic table
