| Tiivistelmä: | Exponential smoothing /ES/ is the most widely used among the extrapolative forecasting techniques. Several forecasting methods based on ES with an underlying seasonal auto-regressive-moving average /SARIMA/ model are discussed. Relations between smoothing constants and the coefficients of the auto-regressive and moving average polynomials are used, and a maximum likelihood estimation is described. This new approach does not need initial smoothed values. Prediction intervals are also obtained as a by-product of the procedure, and an algorithm for implementing this model is presented briefly. |
