- We focus on models from size 8 to 12 risk factors. The AIC difference is calculated as Δi=AICi−AICmin. Starting from values of Δi>4 the level of empirical support of model i, with respect to the best model, is considerably less (see [94] ch.2 for a detailed explanation). We highlight in bold the AIC differences related to the models for which there is a substantial empirical support (i.e. Δi<4)
