Use the Compare Designs Model section to add or remove model effects to compare your designs. The Model section initially lists effects that are in the Model script of the reference design table and that are estimated by all designs being compared. If there is no Model script in the reference design table, the Model section shows only the main effects that can be estimated by all designs being compared. For more information about how to add and remove effects, see “Model”.
Note: For supersaturated designs, where the number of parameters to be estimated exceeds the number of runs, the Model section lists only a set of effects that can be estimated.
Use the Compare Designs Alias Terms section to add or remove effects to compare your designs for active effects. The Alias Terms section initially contains all two-factor interactions that are not in the Model section. The effects in this section impact the calculations in the Alias Matrix Summary and Absolute Correlations section. See Alias Matrix Summary and Absolute Correlations.
For more information about how to add and remove effects, see “Alias Terms”.
