WebMay 17, 2024 · R model fitting functions generally have a predict method associated with them. That just means that the predict function will return appropriate predictions for the type of model object you give it. In this case, the tseries package has an associated predict method for garch model objects.

WebOct 14, 2024 · To fit the model I used ugarchfit () function from the 'rugarch' package in R. The parameters are chosen in such a way that the AIC is minimized. Strangely, the AIC is now -3.4688 indicating the ARIMA model was MUCH better than ARIMA-GARCH, which I thought was too big of a difference. I took a deeper look and found this: WebAug 1, 2024 · I want to export the results of a GARCH model fitted with the package rugarch to latex but I cannot find a suitable package for it.
