Using a particular set of data, 3 types of forecasting methods were used on that data set? The first forecasting method used was a 3 week simple moving average and the MSE of the data set using this method was found to be 310. The second forecasting method used was a 3 week weighted moving average and the MSE of the data set using this method was found to be 349. The third forecasting method used was an exponential smoothing method and the MSE of the data set using this method was found to be 329. When comparing the MSE of each method, which forecasting method is the most accurate of the three?
A Exponential smoothing method
B 3 week weighted moving average
C 3 week simple moving average
D All three methods are equally accurate
