Given the following data, use exponential smoothing with a = 0.2 and a = 0.5 to generate forecasts for periods 2 through 6. Use MAD and MSE to decide which of the two models produced a better forecast. (Round your answers to 2 decimal places, e.g., 2.25.) Period Actual Forecast 1 15 17 2 16 3 17 4 10 5 12 ol 6 16 16 Forecast Period Actual a = 0.2 a = 0.5 1 15.00 17.00 17.00 2 16.00 3 17.00 4 10.00 5 12.00 6 16.00 MAD: MSE: Exponential smoothing using a = yields lower MAD. Exponential smoothing using a = yields lower MSE
