Simple exponential smoothing prediction model

WebbSimple exponential smoothing always gives a flat forecast since all forecasted values are equal to the first forecasted value (i.e. y(t+k) = y(t+k-1) =....y(t+1), for all k > 1). This can … WebbExponential smoothing is useful when one needs to model a value by simply taking into account past observations. It is called "exponential" because the weight of past observations decreases exponentially. This method it is not very satisfactory in terms of prediction, as the predictions are constant after n+1.

(See [TS] arima for fitting ARIMA models in Stata.)Chatfield(2001, 90) gives the following useful derivation that relates the MA coefficient in an ARIMA (0,1,1) model to the smoothing parameter in single-exponential smoothing. An ARIMA (0,1,1) is given ...

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.
