When measuring forecast accuracy, MSE emphasizes larger errors by
| A. |
Doubling the error |
|
| B. |
Dividing by the number of periods |
|
| C. |
Using the absolute value of the error |
|
| D. |
Squaring the error |
Homework Answers
The correct option is D. Squaring the error as MSE(Mean Square Error), takes the square of each error then add then to get the forecast accuracy.
