The [B/D] FAQ




    What is [B/D]?

[B/D] is an interactive programming language, developed by David Wooff and Michael Goldstein, which allows complete a priori and diagnostic analyses of Bayes linear statistical problems. Bayes linear problems are subjective statistical analyses based on expectation and covariance structures, rather than on distributional assumptions. [B/D] is the primary tool of the Bayes linear research group.

What does it do?

[B/D] provides an environment in which we quickly and easily specify beliefs about quantities of interest, attach data to some or all of those quantities, and carry out the general process of Bayes linear adjustment. There is a great deal of information available about the adjustments, and diagnostics for conflicts between the data and your prior beliefs. It is also possible to produce interactive Bayes linear influence diagrams for the adjustments, providing simple graphical summaries of the adjustments and accompanying diagnostics.

What does it run on?

It runs on DOS, Windows, UNIX and X-Windows platforms. The version released to the academic community is a 16-bit  Windows version, but other versions are available.

Will it be free?

The Windows version available here is free. A handling charge will apply to any physical material available. See general information for details.
