Usage Note 35417: How do I create a design with a continuous factor that has more than 2 levels in JMP®?
There are two different approaches that a user can take to create a continuous factor with more than 2 levels.
Approach I: The more highly recommended method
- Select Custom Design from the DOE menu.
- Add all of your factors including the multi-level continuous factor(s).
- Click Continue.
- Select powers 2,3,(4) if necessary to form effects in model. Adding power terms will add more levels to your continuous factor. For 3 levels, add the second power.
- Under Design Generation, enter the number of runs.
- Click on Make design. Do not worry if there are design points at which you can not run the design.
- Inspect the Variance Prediction.
- Select Make Table.
- For designs where you want to specify the levels of the continuous factor, change them in the data table.
- Select Augment Design from the DOE menu.
- Identify the Xs and Identify Y.
- Click Augment.
- Enter the Number of Runs.
- Select Make Design.
- Examine the Variance Prediction
Note: This approach is optimal to some models, just not to the original design.
Approach II: not as highly recommended
- Specify the continuous factor as a categorical factor with the appropriate number of levels.
- Change the values of L1--LN to the values you desire.
- Select Make Design.
- Select Make Table.
- In the data table, change the role from categorical to continuous, nominal to numeric, and remove the design role property.
- Select Augment Design from the DOE menu.
- Identify X factors and Identify Y factors.
- Select Augment.
- Build power terms in the model.
- Select Make Design.
- Examine the Prediction Variance.
