Email: You can ask package related questions to the R mailing-list. 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.

The user provides her own Matlab function to calculate the "sum-of-squares" function for the likelihood part, e.g. a function that calculates minus twice the log likelihood, -2log(p(θ;data)). Optionally a prior "sum-of-squares" function can also be given, returning -2log(p(θ)).
