Formula for the Akaike Information Criterion Image by Author The AIC formula is built upon 4 concepts which themselves. Web How to use AIC in practice To apply AIC in practice we start with a set of candidate models and then find the models corresponding AIC values. Web For this purpose Akaike weights come to hand for calculating the weights in a regime of several models.
Web Looking at p-values of the predictors in the ranked models in addition to the AIC value eg. AIC should be taking into account the DFs. As long as the same value of the constant is used when comparing AICs for different models it doesnt matter.
