The Prediction Profiler report shows the quadratic behavior of the response surface along traces for X1 and X2. Because the Response Limits column property is set for Y, the profiler also shows desirability functions.
Figure 3.15 Prediction Profiler with Match Target as Goal
The goal for the Response Limits column property is set to Match Target. But for this example, you are interested in minimizing Y, not matching a target. Change this setting as follows:
2.
|
In the Response Goal dialog, select Minimize from the list of options.
|
3.
|
Click OK.
|
4.
|
Click the Prediction Profiler red triangle and select Optimization and Desirability > Maximize Desirability.
|
Settings within the design region that minimize Y appear under the profiler. Note that these are precisely the Critical Values given in the Solution report.
