datasets

eco is a publicly available R package that fits the
             parametric and nonparametric Bayesian models for
             ecological inference in 2x2 tables. The models are fit
             using the Markov chain Monte Carlo algorithms that are
             described in Imai and Lu (2004, 2005).
