Fractional Factorial Designs

Optimizing Responses

You can optimize the responses for a regular fractional factorial design by following the process described in the section "Optimizing Multiple Responses". To open the optimization window, click Optimize in the main design window. The prediction profiler will appear, and it can be used in the same way as described in Chapter 3. In this case, setting SSPD at the lowest level will minimize the shrinkage. The other factors can be set according to other criteria without significantly affecting shrinkage.
