This package consists of R functions developed at the Political Science Computational Laboratory at Stanford University; it currently includes models for count data (hurdle regression and zero-inflated negative binomial and Poisson models), ordinal probit and logit (also available in MASS via polr), and an item-response theory model. Also included are Vuong tests for non-nested hypothesis testing and convenience functions for handling roll-call vote matrices.
