a) Assuming an initial forecast for week 1 of 15,000 miles, use exponential smoothing to compute miles for weeks 2 through 12 . Use =0.18 (round b) The MAD for this model = 2.62 thousand (round your response to two decimal places). c) Compute the Cumulative Forecast Errors, cumulative MAD in thousands, and tracking signals (round your responses to two decimal places). a) Assuming an initial forecast for week 1 of 15,000 miles, use exponential smoothing to compute miles for weeks 2 through 12 .
