WebbFor this reason, simple exponential smoothing often performs better out-of-sample than might otherwise be expected, despite its "naive" horizontal trend extrapolation. Damped trend modifications of the linear exponential smoothing model are also often used in practice to introduce a note of conservatism into its trend projections.
