Webcorrections such as AIC (Akaike, 1973), DIC (Spiegelhalter et al., 2002, van der Linde, 2005), and, more recently, WAIC (Watanabe, 2010), and all these can be viewed as approximations to different versions of cross-validation (Stone, 1977). At the present time, DIC appears to be the predictive measure of choice in Bayesian applications,

After a bit of messing around, I think the following is the case. First, the DIC deviance is obtained using a discrete set of samples to the main parameter estimates.
