Goodness-of-fit statistics via DIC.

Model	Dbar	Dhat	pD	DIC
Bivariate ordered probit (BOP)	11417.1	11386.9	30.1	11447.2
Zero-inflated BOP	11301.1	11270.3	29.8	11329.9

Dbar: Posterior mean of deviance, Dhat: Deviance evaluated at the posterior mean of the parameters, pD: Dbar-Dhat, the effective number of parameters, and DIC: Deviance information criterion.
