EXAMPLES OF INFERENCE FOR LOCATIONS OF SOURCES OF ATMOSPHERIC CONTAMINATION. The 'src' module is used to perform inference for models of the spread of atmospheric contaminants from point sources. Reference is in src.doc and related files. Some tutorial examples are here. The documentation and examples on the general operation of this package for flexible Bayesian modeling should also be consulted. Files containing the commands used in these examples can be found in the 'ex-src' directory (in slightly more general form). That directory also has the source for some R functions and scripts for plotting results. Note that the 'xgraph' program (distributed via my web page) is very useful for monitoring the progress of MCMC runs, and for producing other plots. The first example shows how test data can be generated from a model with specified parameter values. It should read first, since it introduces the basic specification commands. The subsequent examples show how such data can be fitted, with either a fixed or variable number of sources.
