WinBUGS Development Interface (WBDev): The WinBUGS Development Interface (WBDev) has been designed to enable WinBUGS 1.4 users to implement their own specialized functions and (univariate) distributions by ’hard-wiring’ them into the system via compiled Pascal code. The main reason for doing this is that ’hard-wired’ components are both faster and much more flexible than their ’BUGS-language’ counterparts. Please see the article here for full details and rationale. Ruud Wetzels at the University of Amsterdam has kindly provided a WBDev tutorial. It has been aimed mainly at social scientists but will appeal to a much wider audience. Please click here to access the tutorial, and forward any feedback/queries to Ruud directly.
