**Question:** Using your own words, what are some of the problems and drawbacks of the moving average forecasting model? --- **Discussion:** The moving average forecasting model is a simple method used to smooth out fluctuations in data to predict future values. However, it has several drawbacks: 1. **Lag in Response**: Moving averages tend to lag behind actual data because they are based on past observations. This can result in delays in detecting trends or changes in direction. 2. **Sensitivity to Outliers**: While moving averages can smooth out minor fluctuations, they can be significantly affected by outliers, which can distort the model's accuracy. 3. **Data Dependency**: The model relies entirely on historical data, assuming that future patterns will mirror past trends, which may not always be the case. 4. **Lack of Flexibility**: Moving averages do not adjust well to rapidly changing circumstances or irregular patterns, as they apply equal weight to all observations in the dataset. 5. **Complexity in Longer Time Frames**: As the time period used for the moving average becomes longer, the model becomes less responsive to recent changes, which may be critical in dynamic environments. These limitations suggest that while moving averages are useful for simple trend analysis, they might not be suitable for intricate forecasting needs without complementary methods.
