Summary: | The Akaike information criterion, AIC, and the Mallows' Cp criterion have been proposed as approximately unbiased estimators for their risks or underlying criterion functions. In this paper we propose modified AIC and Cp, for selecting multivariate linear regression models. Our modified AIC and modified Cp are intended to reduce bias in situations where the collection of candidate models includes both underspecified and overspecified models. In a simulation study it is verified that the modified AIC and modified Cp provide better approximations to their risk functions, and better model selection, than AIC and Cp. |
