7 reel casino. h2. Mean Forecast Error (MFE)

Forecast Bar 2 7 26
Ideal value = 0;
MFE > 0, model tends to under-forecast
MFE < 0, model tends to over-forecast
h2. Mean Absolute Deviation (MAD)
For n time periods where we have actual demand and forecast values:
While MFE is a measure of forecast model bias, MAD indicates the absolute size of the errors
Example
Period | Demand | Forecast | Error | Absolute Error |
---|---|---|---|---|
3 | 11 | 13.5 | -2.5 | 2.5 |
4 | 9 | 13 | -4.0 | 4.0 |
5 | 10 | 10 | 0 | 0.0 |
6 | 8 | 9.5 | -1.5 | 1.5 |
7 | 14 | 9 | 5.0 | 5.0 |
8 | 12 | 11 | 1.0 | 1.0 |
n = 6 observations | Period | Demand | Forecast | Error | Absolute Error |
---|---|---|---|---|---|
3 | 11 | 13.5 | -2.5 | 2.5 | |
4 | 9 | 13 | -4.0 | 4.0 | |
5 | 10 | 10 | 0 | 0.0 | |
6 | 8 | 9.5 | -1.5 | 1.5 | |
7 | 14 | 9 | 5.0 | 5.0 | |

MFE = -2/6 = -0.33
MAD = 14/6 = 2.33
Conclusion: Model tends to slightly over-forecast, with an average absolute error of 2.33 units.
