Consider the following time series data. Week 1 2 2 3 4 5 6 Value 18 13 16 11 17 14 b. Develop the three-week moving average forecasts for this time series. Compute MSE and a forecast for week 7 (to 2 decimais if necessary) MSE The forecast for week 7 c. Use a = 0.2 to compute the exponential smoothing forecasts for the time series. Compute MSE and a forecast for week 7 (to 2 decimals) MSE The forecast for week 7 d. Compare the three-week moving average approach with the exponential smoothing approach using a = 0.2 Which appears to provide more accurate forecasts based on MSE? Explain The three week moving average provides a Select your answer forecast than the exponential smoothing approach since it has a Select your answer MSE e. Use a smoothing constant of a = 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? Explain The exponential smoothing forecast using a 0.4 provides a Select your answer forecast than the exponential smoothing forecast using a 02 since it has a Select your answer. MSE
