| a. |
Calculate the Mean Absolute Deviation for F1 and F2. Which is more accurate? (Round your answers to 2 decimal places.) |
| MAD F1 | |
| MAD F2 | |
| (Click to select)F1F2None appears to be more accurate. |
| b. |
Calculate the Mean Squared Error for F1 and F2. Which is more accurate? (Round your answers to 2 decimal places.) |
| MSE F1 | |
| MSE F2 | |
| (Click to select)F2F1None appears to be more accurate. |
| c. |
You can choose which forecast is more accurate, by calculating these two error methods. When would you use MAD? When would you us MSE? Hint: Control charts are related to MSE; tracking signals are related to MAD. |
|
Either one might already be in use, familiar to users, and have past values for comparison. If (Click to select)control chartstracking signals are used, MSE would be natural; if (Click to select)tracking signalscontrol charts are used, MAD would be more natura |
| d. |
Calculate the Mean Absolute Percent Error for F1 and F2. Which is more accurate? (Round your intermediate calculations to 2 decimal places and and final answers to 2 decimal places.) |
| MAPE F1 | |
| MAPE F2 | |
| (Click to select)F1F2None appears to be more accurate. |
