In this paper, we show the validity of the adaptive least absolute shrinkage and selection operator (LASSO) procedure in estimating stationary … WebThe high p-values give no reason to reject the hypothesis that the log-returns are a GARCH white noise process. In other words, there is no need to ARMA modelling. 4. Fitting GARCH(1,1) models and their variants Based on the discussion above, we go on to t GARCH model(s), starting with a GARCH(1,1) model with Gaussian innovations.
