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. See src.doc and linked files for general information before looking at these tutorial examples. 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. 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.
