Exponential smoothing with a = 0 G Let the initial forecast foryear 1 be 41' the same as the actual demand Exponential smoothing with = 0 '3 Let the initial forecast foryear 1 be 41' the same as the actual demand rend projection with regression or iv. Two-year moving average v. Two-year weighted moving average using weights 0 6 and 0 4' with the more recent data given more weight If MAD is the performance criterion chosen by the administration which forecasting method should it choose? V If MSE is the performance criterion chosen by the administration which forecasting method should it choose?
