Webb28 dec. 2016 · However, we can also use smoothing to fill in missing values and/or conduct a forecast. In this issue, we will discuss five (5) different smoothing methods: weighted moving average (WMA), simple exponential smoothing, double exponential smoothing, linear exponential smoothing, and triple exponential smoothing. WebbExponential smoothing weights past observations with exponentially decreasing weights to forecast future values This smoothing scheme begins by setting \(S_2\) to \(y_1\), where \(S_i\) stands for smoothed observation or EWMA, and \(y\) The subscripts refer to the time periods, \(1, \, 2, \, \ldots, \, n\). and so on. There is no \(S_1\);
