Transcribed Image Text:### Forecasting Method Comparison Table
The following table presents the error metrics for various forecasting methods. The methods are compared using four different error metrics: RSFE, MFE, MAPE, and SDFE.
| **Method** | **(6,4,3,2)** | **3P avg** | **Alpha 0.3** | **SMA** |
|--------------|--------------|-------------|---------------|---------|
| **RSFE** | -26 | -15 | -2 | -13 |
| **MFE** | -6.5 | -3 | -0.4 | -2.1 |
| **MAPE** | 16.22 | 12.11 | 14.21 | 15.3 |
| **SDFE** | 1.5 | 11.26 | 11.3 | 12.2 |
**Key:**
- **RSFE (Running Sum of Forecast Errors)**: This indicates the accumulated sum of errors in the forecast.
- **MFE (Mean Forecast Error)**: This measures the average forecast error over a period.
- **MAPE (Mean Absolute Percentage Error)**: This indicates the average absolute percentage error of the forecasts.
- **SDFE (Standard Deviation of Forecast Error)**: This measures the dispersion or variability in forecast error values.
**Explanation of Methods:**
1. **(6,4,3,2)**: Possibly a weighted moving average with respective weights.
2. **3P avg**: Three-period moving average.
3. **Alpha 0.3**: Exponential smoothing with a smoothing constant (alpha) of 0.3.
4. **SMA**: Simple Moving Average.
This table helps in understanding and comparing the accuracy of different forecasting methods based on various error metrics, aiding in selecting the most appropriate method for a given dataset.
