Available Central Composite Designs

The available central composite designs are shown next. This information is applicable to designs with standard response data, as well as robust parameter designs and reliability DOE.

This table provides information about how many corner point (i.e., factorial) runs will be used in the design, based on the number of factors and the selected fractionality of the design, as well as how many center points will be used by default when a single block is used. For example, if you are using 5 factors and have selected a full factorial design, the design will use 32 corner point runs and will use 10 center points by default, provided that only a single block is used. If you are using 5 factors and have selected a half fraction design, the design will use 16 corner point runs and will use 6 center points by default, provided that only a single block is used.
