WebThe goal of using AIC or BIC is to find the model that will do the best on future data. But cross-validation already gives you a pretty good idea of which models do well on future … 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
