The Augment Design red triangle menu has several options, many of which are commands for saving and loading information about variables. They are available in all designs and more information is in Special Custom Design Commands. The following sections describe commands found in this menu that are specific to augment designs.
To create a script and save it as a table property in the JMP design data table, click the red triangle icon in the Augment Design title bar and select Save X Matrix. Two or three scripts are saved to the table. Moments Matrix and Design Matrix scripts are always saved. If the design is a split plot design, an additional V Inverse script is also saved. When you run the Moments Matrix script, JMP creates a matrix called Moments and displays its number of rows in the log. When you run the Design Matrix script, JMP creates a matrix called X and displays its number of rows in the log. When you run the V Inverse script, JMP creates the inverse of the variance matrix of the responses, and displays its number of rows in the log. If you do not have the log visible, select View > Log or Window > Log on the Macintosh.
Modify the Design Criterion (D- or I- Optimality)
To modify the design optimality criterion, click the red triangle icon in the Augment Design title bar and select Optimality Criterion, then choose Make D-Optimal Design, Make I-Optimal Design, or Make Alias Optimal Design. The default criterion for Recommended is D-optimal for all design types unless you have used the RSM button in the Model panel to add effects that make the model quadratic.
To override the default number of random starts, click the red triangle icon in the Augment Design title bar and select Number of Starts. A window appears with an edit box for you to enter the number of random starts for the design you want to build. The number you enter overrides the default number of starts, which varies depending on the design.
Augment designs can be constrained to a hypersphere. To edit the sphere radius for the design in units of the coded factors (–1, 1), click the red triangle icon in the Augment Design title bar and select Sphere Radius. Enter the appropriate value and click OK.
In addition to linear inequality constraints on continuous factors and constraining a design to a hypersphere, you can define general factor constraints on the factors. You can disallow any combination of levels of categorical factors if you have not already defined linear inequality constraints.
