Introduction WebMay 20, 2024 · The Akaike information criterion (AIC) is a metric that is used to compare the fit of several regression models. It is calculated as: AIC = 2K – 2ln(L) where: K: The number of model parameters. The default value of K is 2, so a model with just one predictor variable will have a K value of 2+1 = 3. ln(L): The log-likelihood of the model. WebGabauer (2024): DCC-GARCH connectedness.
