Webb24 dec. 2024 · We know that AIC formula for linear regression models is the following: A I C = 2 k + n log ( R S S / n). where k is the number or estimated parameters (degrees of freedom) and n is the sample size. So we can easily calculate AIC value for all three models. And I have two questions: 1. Can I compare AIC's values of these models and …
