Week Value Forecast 1 16 2 15 16.00 17 15.80 4 13 16.06 16 15.63 13 15.55 MSE: 3.70 The forecast for week 7: 15.04 d) Compare the three-week moving average forecast with the exponential smoothing forecast using a = 0.2. Which appears to provide the better forecast based on MSE? Exponential Smoothing Explain. The input in the box below will not be graded, but may be reviewed and considered by your instructor. Exponential smoothing is better due to smaller MSE. e) Use trial and error to find a value of the exponential smoothing coefficient a that results in a smaller MSE than what you calculated for a = 0.20. Use a two-decimal digit precision. alpha: 0.2
