"Suppose that we have a statistical model of some data. Let k be the number of estimated parameters in the model. Let be the maximized value of the likelihood function for the model. Then the AIC value of the model is the following. Given a set of candidate models for the data, the preferred model is the one with the minimum AIC value. Thus, AIC rewards goodness of fit (as assessed by the likelihood function), but it also … " - Good fit aic

WebJul 19, 2024 · AIC compares the relative “quality” of a model (distribution) versus the other models. You can use AIC to select the distribution that best fits the data. The distribution with the smallest AIC value is usually the preferred model. AIC is defined as the following: AIC = 2k – 2 (Log-Likelihood) where k is the number of parameters.
