WebFeb 6, 2024 · α = smoothing factor of data which is 0 < α < 1 t = time period Double Exponential Smoothing It is also known as Holt’s trend corrected or second-order exponential smoothing. This method is used to forecast the time series when the data has a linear trend with no seasonal pattern. WebThe simple exponential smoothing forecast model uses the following equation: Last period's forecast + α (Last period's demand - last period's forecast), where α = the smoothing constant. Therefore, in this case: Last period's forecast = 99 α = .4 Last period's demand = 103 99 + .4 (103 - 99) = 100.6
