🗑
|
||||
| Mean Absolute Deviation (MAD) | Measure of forecast error that computes error as the average of the sum of the absolute errors.
🗑
|
||||
| Mean Squared Error (MSE) | Measure of forecast error that computes error as the average of the squared error.
🗑
|
||||
| Forecast Bias | A persistent tendency for a forecast to be over or under the actual value of the data.
