Post hoc Bayesian model selection
This note describes a Bayesian model selection or optimization procedure for post hoc inferences about reduced versions of a full model. The scheme provides the evidence (marginal likelihood) for any reduced model as a function of the posterior density over the parameters of the full model. It rests upon specifying models through priors on their parameters, under the assumption that the likelih...

متن کاملPost-hoc selection of dynamic causal models
Dynamic causal modelling (DCM) was originally proposed as a hypothesis driven procedure in which a small number of neurobiologically motivated models are compared. Model comparison in this context usually proceeds by individually fitting each model to data and then approximating the corresponding model evidence with a free energy bound. However, a recent trend has emerged for comparing very lar...
متن کاملBayesian Model Selection
Traditionally, Bayes factors, posterior odds and posterior model probabilities are used in Bayesian model selection. This approach has, however, the problem that the conclusions are often too sensitive to prior specifications. Another approach is to use discrepancy measures in model comparison and posterior predictive checks in the assesment of model adequecy. These approaches are briefly summa...
متن کاملRobust Bayesian Model Selection
This paper extends the robust Bayesian inference in misspeci ed models of Müller (2013, Econometrica) to Bayesian model selection of a set of misspeci ed models. It is shown that when a model is misspeci ed, under the Kullback-Leibler loss function, the risk associated with Müllers posterior is less (weakly) than that with the original posterior distribution asymptotically. Based on this new r...
