(e) Use a = 0.4 to compute the exponential smoothing values for the time series. Time Series Value Week 1 2 im 3 4 5 6 18 11 10 17 15 Forecast A Does a smoothing constant of 0.2 or 0,4 appear to provide more accurate forecasts based on MSE? Explain. The exponential smoothing using a = 0.4 provides a better forecast since it has a larger MSE than the exponential smoothing using a = 0.2. The exponential smoothing using a = 0.2 provides a better forecast since it has a smaller MSE than the exponential smoothing using a = 0.4. The exponential smoothing using a The exponential smoothing using a 0.4 provides a better forecast since it has a smaller MSE than the exponential smoothing using a = 0.2. 0.2 provides a better forecast since it has a larger MSE than the exponential smoothing using a 0.4.1
