WebbThe adaptive-response-rate single exponential smoothing algorithm may have an advantage over single exponential smoothing in that it allows the value of alpha to be modified. For single exponential smoothing, let St be the smoothed value for the t-th time period. Mathematically: S1 = x0. St = αxt−1 + (1−a)St−1. Webb1 sep. 2011 · The simple exponential smoothing model is one of the most popular forecasting methods that we use to forecast the next period for a time series that have no pronounced trend or seasonality. below...
