Understanding predictive information criteria for Bayesian models

http://www.stat.columbia.edu/~gelman/research/published/waic_understand3.pdf The deviance information criterion (DIC) is a hierarchical modeling generalization of the Akaike information criterion (AIC). It is particularly useful in Bayesian model selection problems where the posterior distributions of the models have been obtained by Markov chain Monte Carlo (MCMC) … See more In the derivation of DIC, it is assumed that the specified parametric family of probability distributions that generate future observations encompasses the true model.

WebDIC is a Bayesian version of AIC. Like AIC, it trades o a measure of model adequacy against a measure of complexity and is concerned with how replicate data predict the observed data. Unlike AIC, DIC takes prior information into account. DIC is constructed based on the posterior distribution of the log-likelihood or the deviance,
