AIC information criterion, that is, Akachi information criterion, is a standard to measure the goodness of fit of statistical models. Because it was founded and developed by Japanese statistician Hiroshi Akachi, it is also called Akachi Information Criterion. Based on the concept of entropy, it can measure the complexity of the estimation model and the goodness of the model fitting data.

AIC index is one of the commonly used indexes in trend estimation and prediction model, and the other three main indexes are mean square error (MSE), S 2 and Schwartz information criterion (SiC). The productivity factors of S 2 and SIC are (T/T-K) and t (k/t) respectively.
