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, but the values ​ ​ of α and vulnerable to subjective effects such reasonable method to determine the value of α is very important, in general, if the data fluctuations, α values ​ ​ should be taken a bit more, you can increase the impact of the recent data on the predicted results. If the data fluctuations smooth, α values ​ ​ should take smaller.
