I am also interested in how Bayesian model averaging can be used as the basis for model-building strategies that take account of model uncertainty, providing an alternative to stepwise regression and related methods. My focus is on the practical implementation of these methods for model classes that arise in scientific applications, particularly in the social and health sciences. Hoeting et al (1999) give a review of Bayesian model averaging. For a discussion in the context of social science applications, which also exposits Bayes factors and the basis for the simple BIC approximation, see Raftery (1995). The Bayesian Model Averaging Homepage includes articles on BMA and free software for carrying it out.

Most recently, I have worked on extending Bayesian model averaging beyond statistical models to the dynamical deterministic simulation models that predominate in some environmental, engineering and policy-oriented disciplines. One motivation is to develop calibrated probabilistic weather forecasting methods using forecast ensembles (Raftery et al 2005).
