Description: Single exponential smoothing refers to a first end of exponential smoothing. If in order to make the exponential smoothing value is sensitive to reflect changes in the latest observations, should take a larger Alfa value, if the exponential smoothing value is used to the long-term trend represents the values of the time series, should take the smaller Alfa value. At the same time, the market forecast, also should take different Alfa value, according to changes in long-term trend and seasonal changes of different in general, shall be treated according to the following situation: 1 if the long-term trend observed values close to constant changes, should take the middle value (generally 0.6- 0.4) to observe value has a size close to the weight in the index smoothing 2 if the observed values showed clear seasonal changes, it is desirable to take larger values (usually 0.6- 0.9), the recent observation has important role in exponential smoothing value, thereby enabling the observation valu
