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 13 17 2 15 3 17 10 12 18 Period Actual 4 5 6 a=0.2 Forecast a=0.5 Period Actual 1 13.00 2 15.00 17.00 10.00 12.00 18.00 MAD: MSE: 3 4 5 6 a=0.2 17.00 a=0.5 17.00 Exponential smoothing using a= Exponential smoothing using a = yields lower MAD. yields lower MSE
