Response Surface Design (Central Composite): Use to create a factorial or fractional factorial design that includes center points, augmented with a group of axial points (also called star points) that let you estimate curvature
Create
Response Surface Design (Box-Behnken): Use to create a response surface design with treatment combinations that are at the midpoints of the edges of the experimental space and at least three continuous factors. Box-Behnken designs do not contain an embedded factorial or fractional factorial design.
