Choice Design Options

Save Factors

Saves the information in the Factors panel to a new data table. Each factor’s column contains its levels. Other information is stored as column properties. You can then quickly load the factors and their associated information into most DOE windows.

Note: It is possible to create a factors table by entering data into an empty table, but remember to assign each column an appropriate Design Role. Do this by right-clicking on the column name in the data grid and selecting Column Properties > Design Role. In the Design Role area, select the appropriate role.

Load Factors

Loads factors that you saved using the Save Factors option.

Set Random Seed

Sets the random seed that JMP uses to control actions that have a random component. These actions include one or more of the following:

initializing search algorithms for design generation

randomizing Run Order for design construction

selecting a starting design for designs based on random starts

To reproduce a design, enter the random seed that generated the design before clicking Make Design.

Note: The random seed associated with a design is included in the DOE Dialog script that is saved to the design data table.

Simulate Responses

Adds response probabilities and a column containing a choice simulation formula to the design table. Select this option before you click Make Table.

When you click Make Table, the following occur:

A new column that contains a simulated choice response formula is added to the design table. The formula and values are based on the model that is specified in the design window.

A Model window appears where you can set the values of the marginal utilities for model effects.

A script called Choice Simulate is saved to the design table. This script reopens the Model window, enabling you to re-simulate values or to make changes to the marginal utilities.

When you click Apply, the formula for the simulated choice response values is updated in the Choice Simulated column. If you click Apply again, the formula and values in this column are updated.

See Simulate Responses in the Custom Designs section.

Note: You can use Simulate Responses to conduct simulation analyses using the JMP Pro Simulate feature. For more information and DOE examples, see Simulate in Basic Analysis.

Number of Starts

Enables you to specify the number of random starts used in constructing the design. See Bayesian D-Optimality and Design Construction.

Advanced Options

Not available for Choice Designs.

Save Script to Script Window

Creates the script for the design that you specified in the Choice Design window and saves it in an open script window.
