Computation for Bayesian Tree Models
Casper Wu, Håkon Tjelmeland & Mike West

This site provides C++ code implementing Metropolis Hastings MCMC methods for exploring spaces of Bayesian classification and regression tree models, and developing posterior and predictive inference using Bayesian model averaging over many tree models.

The code implements models and methods as described in

  • the paper "Bayesian CART: Prior specification and posterior simulation" Journal of Computational and Graphical Statistics, (2007, to appear), by Wu, Tjelmeland and West, and

  • the 2006 PhD thesis "Bayesian Tree Models", by Yuhong (Casper) Wu.

The code, with a readme file of details, is freely available to anyone interested. The readme includes details of compilation and use, including a small example with input data and parameter files, and description of output files.
