Exponential Smoothing MethodThe original number data is as follows:Click Data--Data analysisSelect exponential SmoothingBest-in- one smoothingSince the area we selected was b1:b22, the first cell "steel output" was used as a sign, so we should tick the mark. When we tick the flag, the first cell in the column is not used for the calculation, and the calculation starts with the second cell. The results are as follows:do two smoothinghere, we no longer use flags, so the data range is selected in C3:c22Comparedamping coefficient =0.3damping coefficient =0.05damping coefficient =0.9drawing on a graph in contrast, the greater the visible damping coefficient, the more flat the curve. moving average (first and second order)Similarly, you can use Excel to calculate the following table:Related data files:
