For (1)-(4) below, compute the forecasted shipping space required: 1) Using a three month moving average for months 4 through 19. (2 points) 2) Using a three month weighted moving average for months 4 through 19 , with weights 0.5 for the most recent month, 0.3 for the next most recent month and 0.2 for the distant month. ( 2 points) 3) Using exponential smoothing for months 2 through 19 , with =0.8. 2 points) 4) Using adjusted exponential smoothing for months 2 through 19 , with =0.8 and =0.6. (4 points) 5) Compare the accuracy of the above four forecasting models using MAD (mean absolute deviation) (12 points) 6) Which of the four forecasting models / methods would you recommend and why? (3 points)
