Balanced Design Diagnostics

The number of runs in a balanced design appears in the Candidate Runs outline. The Parameter Variance for Balanced Design outline shows the covariance matrix for the parameters for this design. The Distribution Profiler also appears. When you obtain the optimal design, you can compare the Parameter Variance and Distribution Profiler results for the optimal design to those for the balanced design to see the reduction in uncertainty.

2.

From the ALT Plan red triangle menu, select ALT Optimality Criterion > Make Probability I-Optimal Design.

This tells JMP to use the Probability optimality criterion when creating the design in the next step. For details about this criterion, see Make Probability I-Optimal Design.

Click Make Design.

The optimal experimental design is shown, along with other results.

The optimal design is computed based on the levels of the test runs, the total number of units to be tested, and the prior information that you specified. The optimal design consists of testing the following number of units at each torque level:

–

72 units at 50 Nm

–

8 units at 75 Nm

–

20 units at 100 Nm
