Appendix AWinBUGS
BUGS and WINBUGS are distributed freely and are the result of many years of development by a team of statisticians and programmers at the Medical Research Council Biostatistics Research Unit in Cambridge (BUGS and WinBUGS) and recently by a team at University of Helsinki (OpenBUGS); see the project pages:

Models are represented by a flexible language, and there is also a graphical feature, DOODLEBUGS, which allows users to specify their models as directed graphs. For complex models the DOODLEBUGS can be very useful. As of May 2007, the latest version of WinBUGS is 1.4.1, and OpenBUGS 3.0.
A.1 Using WinBUGS
We start the introduction to WinBUGS with a simple regression example. Consider the model
The scale in normal distributions here is parameterized in terms of a precision parameter
that is the reciprocal of variance,
Natural distributions for the precision parameters are gamma, and small values of the precision reflect the flatness (noninformativeness) ...
