Software for Flexible Bayesian Modeling and Markov Chain Sampling

This software supports flexible Bayesian learning of regression, classification, density, and other models, based on multilayer perceptron neural networks, Gaussian processes, finite and countably infinite mixtures, and Dirichlet diffusion trees, as well as facilities for inferring sources of atmospheric contamination and for molecular simulation. These are implemented using Markov chain Monte Carlo methods. Facilities for Markov chain sampling from distributions specified by simple formulas for the density or for the prior and likelihood are also included.

Before trying to use the software, you may need to read various references that describe the models and the Markov chain methods used.

The software is written in ANSI C for Unix, Linux, and macOS systems.

Some of the programs in this package are designed for use with the xgraph plot package for X-Windows, though the data can instead be plotted by whatever plot program you have available.

The source code is now also available at gitlab.

Warning: This version contains a bug in net-pred that affects predictions for multi-way classification models. It can be patched by changing line 392 of net/net-model.c, replacing "type=1" with "type==1". There's also a bug affecting the "n" option for gp-pred for multi-way classification models, which you can patch by replacing "+=" with "=" on line 440 of gp-pred.c.
