Exponential smoothing, with a = 0.9. Let the initial forecast for year 1 be 41, the same as the actual demand iii. Trend projection with regression iv. Two-year moving average. V. Two-year weighted moving average, using weights 06 and 0.4 with the more recent data given more weight. frect: If MAD is the performance criterion chosen by the administration, which forecasting method should it choose?
