"WebEither write down the likelihood function and feed it into a generic optimizer (such as the function optim in R); Or use an existing function that takes the model specification (e.g. ARMA (p,q)-GARCH (s,r)), "writes the likelihood" for you and optimizes it (such as the function ugarchfit in the "rugarch" package in R). Both ways are fine: " - Garch package matlab

WebEDIT: The question refers to forecasting the returns. Using AR-GARCH model, r t = μ + ϵ t. z t = ϵ t / σ t. z t is white noise or i.i.d, and can take any distribution. σ t 2 = w + α ϵ t − 1 2 + β σ t − 1 2. The predict function in R is forecasting r t + k where k is the periods into the future.
