The MaxDiff Study red triangle menu contains the following options:
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
Select this option to simulate response values. When you click Make Table, a Simulate Choice window opens along with the design table, and Probability and Choice Simulated columns are added to the design table. The Choice Simulated formula column contains random responses and the Probability formula column contains their probabilities.
Caution: To change the model used in simulating the responses, enter values in the Marginal Utility column in the Simulate Choice window for all factor levels but the last. Because the marginal utilities must sum to zero, you are not permitted to edit the Marginal Utility for the last level. Once you have specified the remaining Marginal Utility values, the last level of the factor is adjusted accordingly.
Number of Starts
The number of random starts used in constructing the design. This value is set to 10 by default.
Advanced Options
Not applicable for MaxDiff Designs.
Save Script to Script Window
Creates the script for the design that you specified and places in an open script window.
