Merge-Split Samplers for Conjugate Bayesian Nonparametric Models

Markov chain Monte Carlo samplers for posterior simulations of conjugate Bayesian nonparametric mixture models. Functionality is provided for Gibbs sampling as in Algorithm 3 of Neal (2000) , restricted Gibbs merge-split sampling as described in Jain & Neal (2004) , and sequentially-allocated merge-split sampling , as well as summary and utility functions.
