Several forecasting methods were used for the same data set to determine which method worked best. The results are shown in the picture. Use MAD as the criterion, the best method is MAD Method 2 period moving average 3 period moving average 4 period moving average period moving average 6 period moving average Simple exponential smoothing (using best alpha) Linear Regression MSE 2.9 3.63 3.03 3.56 3.05 10.55 15.95 11.02 15.93 11.2 3.22 3.06 15.78 11.55 O 3 period moving average O 6 period moving average O Linear regression O 5 period moving average O 4 period moving average O 2 period moving average O Simple exponential smoothing
