excel - Exponential smoothing on Excel for Mac?

Question

Excel has an exponential smoothing. I have a graph I'd like to smooth, however the Mac version doesn't seem to have this feature.

Is there a way I can smooth the chart - either as a chart feature or by using a formula in additional cells to smooth the chart:?

Answer 1

指数平滑可以使用 MS Excel 中的公式完成。

第一个值（C3）将等于第一个原始值（B3）。

第一个平滑值 (C4)，图中突出显示的公式将等于上面的值一个 (C3) + alpha($C$1)* (下一个原始值 (B4) - 前一个平滑值 (C3)。
