In the Screening Design platform, when you select a fractional factorial design with all continuous or two-level categorical factors, and possibly a blocking factor, the Display and Modify Design section enables you to modify your design. Modify your design using the options in this section. See Example of Modifying Generating Rules in a Fractional Factorial Design for an example of changing the generating rules to construct a design.
Note: The Change Generating Rules and Aliasing of Effects sections do not appear for Plackett-Burman designs or Cotter designs, because interactions are not identically equal to main effects.
Change Generating Rules
Specify the defining relation for the design. The defining relation determines which fraction of the full factorial design JMP provides. See Change Generating Rules.
Aliasing of Effects
Shows the confounding pattern for the fractional factorial design. Click the red arrow at the bottom of the panel to see interactions to a specified order. The interactions and their aliases are presented in a data table.
Coded Design
Shows the pattern of high and low values for the factors in each run.
Note: For Plackett-Burman and Cotter designs, the Change Generating Rules and Aliasing of Effects sections do not apply and are not shown.
