Part C

c) Compute the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your responses to two decimal places) Are the tracking signals within acceptable limits? The control limits for the tracking signal are set at 3 MADs. The tracking signals acceptable limits. a) Assuming an initial forecast for week 1 of 17,000 miles, use exponential smoothing to compute miles for weeks 2 through 12 . Use a =0.25 (rou responses to two decimal places) b) The MAD for this model = thousand (round your rosponse to two docimal places)
