Hello everyone, Maybe i was not too much specific last time: I have a variable "y" that follows a GARCH(1,1) process. Then, i Gretl i type: garch 1 1 ; y const Then i got the result and forecasting the out-of-sample values of y can be done in the usual way. However, i'm interested in forecasting the out-of-sample variance. I don't know if such a function exists in Gretl. Thanks in advance, Alejandro Hello, How can we get the out-of-sample volatility / variance forecasts of a GARCH model? Thank you, Alejandro
