Dear list I am working on designing a project in which we want to use GPS data to track where participants engage in drug or alcohol use and/or where they experience cravings. I am thinking of using a Bayesian approach to developinga kind of probability of use map linking the GPS and participant-reported data (via smart phones). That is, given someone's GPS location, what is the probability of use, or conditional probability based on additional information? Has anyone on the list used WinBUGS for doing something similar to this?
