Weekly tires demand is as follows: 1. First use 2-period moving average model to forecast weeks 3 through 12 and evaluates the results by using MAD, MFE, and MAPE. 2. Estimate demand for the next four weeks (week 13> ) using a five-week moving average, as well as simple exponential smoothing with =0.8 and =0.2. Explain the impact of alpha. 3. Evaluate the results of the exponential smoothing with =0.8 and =0.2. 4. Estimate demand for the next four weeks (week 13> ) using a linear regression model. 5. Develop a regression model with seasonal adjustments for weeks 8 through 12 . Compare with the results of Question 4. Weekly tires demand is as follows: 1.
