3.1.14 Orthogonal Main Effect Design

When the size of the design is of utmost importance Orthogonal Main Effect designs are appropriated. They can be used under the assumption that all interactions between the controls are negligible.

The layout of the sample points can be found in tables listed in [29]. Also tables for mixed levels for the controls can be found.

In Table 3.7 a level 2 Orthogonal Main Effect design with three parameters is shown.
