Smach - Spatial Markov Chain Monte-Carlo

Description

This page documents Smach, code that implements models described in "Model-based Geostatistics" [Diggle, Moyeed and Tawn, Appl Statist 47 , Part 3, pp 299-350]

Aims

Eventually to cover as many possible models with as many possible covariance models. To provide a suite of Splus functions to interface with the MCMC code.

Download

The code is supplied as a gzipped tar file. This is a copy of the CVS repository that I am currently developing on, so there's lots of irrelevant files and I'm not even certain it will compile properly! Just download it and tell me how it goes.

To turn on acceptance counting, add the option: 

accept.count: acceptance.dat
Then for each variable in the model it will write the variable name, the index (for vector-variables), then the number of acceptances and the number of rejections (which should sum to the number of iterations). These values are colon-separated.

Also, some of the option names may have changed. If the program fails, check the source for the correct option names.
