Deviance information criterion (DIC) has been widely used for Bayesian model comparison, especially after Markov chain Monte Carlo (MCMC) is used to estimate candidate models. This paper first studies the problem of using DIC to compare latent variable models when DIC is calculated from the conditional likelihood. In particular, it is shown that the conditional likelihood approach undermines theoretical underpinnings of DIC. A new version of DIC, namely DIC L, is proposed to compare latent variable models. The large sample properties of DIC L are studied. A frequentist justification of DIC L is provided. Like AIC, DIC L provides an asymptotically unbiased estimator to the expected Kullback–Leibler (KL) divergence between the DGP and a predictive distribution. Some popular algorithms, such as the EM, Kalman and particle filtering algorithms, are introduced to compute DIC L for latent variable models. Moreover, this paper studies the problem of using DIC to compare misspecified models. A new version of DIC, namely DIC M, is proposed and it can be regarded as a Bayesian version of TIC. A frequentist justification of DIC M is provided under misspecification. DIC L and DIC M are illustrated using asset pricing models and stochastic volatility models.
