Adding Design Points

In any design, you can add points using the Edit menu. You can specify how many points to add and how to do so: optimally, randomly, or at specified values.

1. Select Edit -> Add Point or click the  button. A dialog appears, as shown.
2. Choose an augmentation method from the drop-down menu: optimal (D,V, or A), random, or user-specified.

Note    You can add points optimally to any design based on a linear or multilinear model, as long as it has the minimum number of points required to fit that model. This means that after adding a constraint you might remove so many points that a subsequent replace operation does not allow optimal addition.

3. Choose the number of points to add, using the buttons or typing into the edit box. For user-specified custom points, you also enter the values of each factor for each point you want to add.
4. If you choose an optimal augmentation method and click Edit, the Candidate Set dialog appears, as shown in the following example. Here you can edit the ranges and levels of each factor and which generation algorithm to use. These are the same controls you see on the Candidate Set tab of the Optimal Design dialog.

   

5. Click OK to add the points and return to the main display.
