The hospital's administration is considering the following forecasting methods. Begin error measurement in year 3 , so all methods are compared for the same years. i. Exponential smoothing, with =0.6. Let the initial forecast for year 1 be 42 , the same as the actual demand. ii. Exponential smoothing, with =0.9. Let the initial forecast for year 1 be 42 , the same as the actual demand. iii. Trend projection with regression. 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?
