[Gretl-devel] Estimating forecast error

Hi I am wondering wether it is possible to estimate forcast error in Gretl in simple terms. Let's fx. say I have a time series on monthy basis and the forecast model is simply some version of lagged values of this same time series (ARIMA,AR etc.). now I want to estimate historical forecast error for one, two, ..., n months in the future or get some data table where one, two, ..., n months forecasts can be compared to real historical values. Is this possible?
