Use a smoothing constant of 0.4 to compute the exponential smoothing forecasts. Does a smoothing constant of 0.2 or 0.4 appear to provide more accurate forecasts based on MSE? Explain. The exponential smoothing using α = 0.4 provides a better forecast since it has a larger MSE than the exponential smoothing using α = 0.2. The exponential smoothing using α = 0.2 provides a better forecast since it has a smaller MSE than the exponential smoothing using α = 0.4.

Compare the three-month moving average approach with the exponential smoothing approach using α = 0.2. Which appears to provide more accurate forecasts based on MSE? The three-month moving average provides a smaller MSE and a more accurate forecast than the exponential smoothing approach. Use a smoothing constant of α = 0.4 to compute the exponential smoothing forecasts. Compute MSE (to 2 decimals). Does a smoothing constant of 0.2 or 0.4 appear to provide more accurate forecasts based on MSE? The exponential smoothing forecast using α = 0.4 provides a smaller MSE than the forecast using α = 0.2.
