1. In the Matrix view, double-click on the "Resale Value"
cell for the "Coyote" truck.
2. Click the "Discrete Distribution" radio button.
3. LDW will display a data entry dialog box for the
discrete distribution.
4. Enter 3 in the "Number of Levels" edit box to tell LDW
there will be three possible discrete levels. Don’t Press
Enter.
5. Enter the levels and their probabilities. Enter 0.25 in the
"Prob 1" edit box and 50 in the "Level 1" to define the
first level-probability combination.
6. Enter 0.5 in the "Prob. 2" edit box, 60 in the "Level 2"
edit box.
7. Enter 0.25 in the "Prob 3" edit box, and 65 in the "Level
3" edit box to complete the definition of the distribution.
8. Click "OK" twice to return to the Matrix view.
Probabilities for Measures With Labels. You can also define
probability distributions for measures that use labels. However,
since continuous distributions are inappropriate, you are
restricted to a discrete distribution over the different labels. To
see how this works, lets define a probability distribution over
"Styling" for the "Mountain Lion" truck:
1. In the Matrix view, click on the "Styling" cell for the
"Mountain Lion" truck.
2. Select the Matrix::Define Probability option.
3. LDW will display the "Define Label Probabilities"
dialog box.
