WebAug 28, 2024 · The Akaike Information Criterion, or AIC for short, is a method for scoring and selecting a model. It is named for the developer of the method, Hirotugu Akaike, and may be shown to have a basis in information theory and frequentist-based inference. WebThe delta for a proposed fit can be converted to an evidence ratio. Anderson gives a table, which can also be found on the Web. One place is page 26 of Burnham, Anderson, Huyvaert's " AIC model selection and multimodel inference in behavioral ecology ", Behav Ecol Sociobiol (2011) 65:23–35 (PDF, accessed 2014-07-11).

WebAIC = 2 k − 2 ln ( L) where k denotes the number of parameters and L denotes the maximized value of the likelihood function. For model comparison, the model with the lowest AIC score is preferred. The absolute values of the AIC scores do not matter. These scores can be negative or positive. WebAIC does not provide a test of a model in the sense of testing a null hypothesis; i.e. AIC can tell nothing about the quality of the model in an absolute sense. If all the candidate models fit ...
