摘要
The standard correction to Akaike's Information Criterion, AICc, assumes the same predictors for training and verification and therefore underestimates prediction error for random predictors. A corrected AIC for regression models containing a mix of random and fixed predictors is derived. (C) 2021 The Author(s). Published by Elsevier B.V.
