Question: With the gasoline time series from Table 15.1, show the exponential smoothing forecasts using alpha = 0.1.

Applying the MSE measure of forecast accuracy, would you prefer a smoothing constant of alpha = 0.1 or alpha = 0.2 for the gasoline time series?
Are the results the same if you apply the MAE as the measure of accuracy?
What are the results if MAPE is used?
