WebThe Akaike information criterion ( AIC) is an estimator of prediction error and thereby relative quality of statistical models for a given set of data. [1] [2] [3] Given a collection of models for the data, AIC estimates the quality of each model, relative to each of the other models. Thus, AIC provides a means for model selection . WebMar 26, 2024 · The Akaike information criterion is calculated from the maximum log-likelihood of the model and the number of parameters (K) used to reach that likelihood. The AIC function is 2K – 2 (log-likelihood). Lower AIC values indicate a better-fit model, and a model with a delta-AIC (the difference between the two AIC values being compared) of …

WebAug 28, 2024 · The Bayesian Information Criterion, or BIC for short, is a method for scoring and selecting a model.

"WebApr 15, 2024 · Roughly I'd say that the AIC is to be preferred if your major aim is prediction quality (as a too big model may still predict well whereas a too small one usually doesn't), whereas the BIC is more motivated by the idea that there is a not too big true model and the aim is to find that.
