| Tiivistelmä: | This paper presents the generalization form of the arbitrary degree exponential smoothing value (ESV) directly with the time series. It points out that the high degree ESV differs from the one degree ESV in the weighted Vector. Then it probes that the arbitrary degree ESV, linea trend exponential smoothing forecasting value (ESFV) and second-degree curve trend ESFV are all the weighted arithmetic mean of the time series. Finally, a new criterion of searching the best smoothing coefficient and a new lower bound formula of the searching interval are proposed. |
