With the gasoline time series data from Table 8.1, show the exponential smoothing forecasts using ?=0.1.

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