Single-exponential-smoothing
- 一次指数平滑法是指以最后的一个第一次指数平滑。如果为了使指数平滑值敏感地反映最新观察值的变化,应取较大阿尔法值,如果所求指数平滑值是用来代表该时间序列的长期趋势值,则应取较小阿尔法值。同时,对于市场预测来说,还应根据中长期趋势变动和季节性变动情况的不同而取不同的阿尔法值,一般来说,应按以下情况处理:1.如果观察值的长期趋势变动接近稳定的常数,应取居中α值(一般取0.6—0.4)使观察值在指数平滑中具有大小接近的权数;2.如果观察值呈现明显的季节性变动时,则宜取较大的α值(一般取0.6一0.9),

logAverage
- 利用计算C#计算指数平均,指数平滑法的计算中,关键是α的取值大小,但α的取值又容易受主观影响,因此合理确定α的取值方法十分重要,一般来说,如果数据波动较大,α值应取大一些,可以增加近期数据对预测结果的影响。如果数据波动平稳,α值应取小一些。-C# calculate index calculated using the average, exponential smoothing method of calculation, the key is the size of α values, bu
