Bayesian analysis is increasingly being used as an analytical technique in epidemiology. The WinBUGS and OpenBUGS software packages are commonly used for these analyses, although other statistical packages (such as MLwIN are also able to use Bayesian methodology.
- WinBUGS code for a variety of situations such as diagnostic test evaluation, disease prevalence estimation and disease presence determination can be found at Bayesian Epidemiologic Screening Technique (BEST) http://www.epi.ucdavis.edu/diagnostictests/home.html
