Deviance information criterion for Bayesian model selection ...

WebThese five model selection methods include AIC, BIC, DIC, AIC corrected for bias (AICc; Sugiura, 1978), and sample-size-adjusted BIC (SABIC; Sclove, 1987). The rest of this article is organized as follows. First, we describe each of the seven model selection methods (AIC, AICc, BIC, SABIC, DIC, LOO, and WAIC) adopted in the current WebDIC is similar to AIC, but its penalty term is based on a complexity term that measures the difference between the expected log likelihood and the log likelihood at the posterior mean point. DIC is designed specifically for Bayesian estimation that involves MCMC simulations.
