Use the Combination forecasting method of the Time Series Forecasting Solver of OM Explorer. Let error analysis begin in month 6, and include (1) a 5-period moving average (with a combination weight of 0.33), (2) an exponential smoothing model with a = 0.20 (with a combination weight of 0.33), and (3) trend projection (with a combination weight of 0.33). What is the MAD of this model? What is the forecast for month 25?
