Tsay rugarch
WebThe rugarch package is the premier open source software for univariate GARCH modelling. It is written in R using S4 methods and classes with a significant part of the code in C and C++ for speed. It contains a number of GARCH models beyond the vanilla version including IGARCH, EGARCH, GJR, APARCH, FGARCH, Component-GARCH, multiplicative ...

WebJust as in fGarch, the rugarch package also enables a non-normality robust coefficient-covariance, ML estimation with non-normal densities, and the joint estimation of an ARMA-specification in the mean together with σt. To the best of my knowledge, no other CRAN-package offers more univariate GARCH-specifications than rugarch.

Note that there does not seem to be an option to use SARMA models in the "rugarch" package, so you will have to let the ...
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.
