The number of mistakes for the past several months appears in this table along with forecasts for errors made with three different forecasting techniques. The column labelled Exponential was created using exponential smoothing with an alpha of 0.30. The column labeled MA is forecast using a moving average of three periods. The column labeled WMA uses a 3-month weighted moving average with weights of 0.65, 0.25, and 0.10 for the most-to- least recent months. Using the following table, determine the CFE for months 4-10 for each forecasting technique. According to the CFE, which technique worked best? (Note - be sure to base your answer on the resulting CFE at the end of period 10, which should incorporate errors in periods 4-10).

The best technique is weighted moving average as their CFE is the least.

The calculated values are shown below. The total CFE is the last value (highlighted in yellow).
