CODA

CODA (Convergence Diagnostics and Output Analysis) is a suite of S functions that provide an object-based infrastructure for analysing the output of Markov Chain Monte Carlo (MCMC) simulations. 

Getting hold of the software

CODA for R is available as an R package from the Comprehensive R Archive Network (CRAN). If you are a unix user, you should install the package from source using the instructions in the R FAQ. If you are a Windows user, you should install the prebuilt binary, also available from CRAN.

CODA for S-PLUS is distributed as an S-PLUS package from the Comprehensive S-PLUS Archive Network (CSAN).

If you use CODA, please cite the paper published in R News. Here is a bibtex entry, including links to the online paper.

Background Reading

The main emphasis of CODA is on convergence diagnostics.   There are two useful reviews of MCMC convergence diagnostics. The first one is by the original author of CODA.
