While the forecast GUI option with OLS and ARIMA provides a printable table of actual, fitted and residual, I can see no way of retrieving and adding the fitted/residuals as seperate series in the data file from the Analysis option. As it is often the case that the dependent variable series is a transformation of another original data series (eg log), it would be helpful if the fitted series displayed in log values could be retrieved to preclude the necessity for creating a new variable and manually entering the data for subsequent reconversion to the original unlogged fitted values. Perhaps there is an option to do this but I cannot see where it might be.
