Summary

Before running WinBUGS, you will need to download it from the WinBUGS website. The latest version of WinBUGS is OpenBUGS, using open source software, which can be obtained at:

http://mathstat.helsinki.fi/openbugs/

Older versions of WinBUGS can be obtained from

http://www.mrc-bsu.cam.ac.uk/bugs/winbugs/contents.shtml

The older versions of WinBUGS require a key for full functionality, which requires that you register (for free). The newer OpenBUGS version does not require a key. Once you have downloaded and installed the software, you are ready to run WinBUGS. The following tutorial is based on the one provided with the program.

A summary of steps for running WinBUGS

  1. Select the term ‘model’ and then ‘check model’.

  2. Select the data and load.

  3. Compile the model.

  4. Set initial values for the Markov chain.

  5. Set variables to be sampled.

  6. Take samples.

  7. Check samples.

The steps in more detail

This tutorial steps through how to analyse a mean in WinBUGS, using the example of estimating the average tree diameter in a park (Box 1.8). It is based on the online User Manual in the WinBUGS program.
