Choose Inner and Outer Array Designs

The Choose Inner and Outer Array Design options appear after you click Continue in the Specify Factors panel. Based on your signal factors, you get one or more choices for orthogonal designs for the inner array. The outer array choices for orthogonal “L” designs depend on the number and type of factors in your design.

Display Coded Design

After you select a design type for the inner and outer arrays, the Coded Design is shown when your inner array has two-level factors.

The Coded Design shows the pattern of high and low values for the factors in each run.
