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. WebOct 8, 2024 · 4. Great answer!

WebJul 30, 2015 · The reason GARCH models are used is because they have a lot of nice properties. The main being that the Conditional Volatility is time-dependent. This means that volatility can cluster. It's true that conditional vol will regress towards "normality" as a random walk process with drift. The second nice property is the closed-form solution allows ...
WebJan 1, 2024 · The margin by which the t-lasso estimators outperform the Gaussian lasso decreases for larger degrees of freedom. In particular, for ν =∞ there is no difference between the t-lasso estimators and the Gaussian lasso. Indeed, as ν→ ∞, a multivariate t-distribution converges to a multivariate normal. The LS suffers from the large number of ...
