Nonorthogonal Designs

The authors suggest the use of D-efficient experimental designs for conjoint and discrete-choice studies, discussing orthogonal arrays, nonorthogonal designs, relative efficiency, and nonorthogonal design algorithms. They construct designs for a choice study with asymmetry and interactions and for a conjoint study with blocks and aggregate interactions.

Nonorthogonal Designs

Recently, at least four methods have been suggested for the analysis of nonorthogonal designs. However, even researchers who have decided which method is appropriate often do not know which computer programs are capable of performing the desired analysis. In addition, available programs differ widely in their accuracy and ease of use. We have evaluated some widely used ANOVA computer programs with respect to their capabilities for performing analyses using all four methods, their accuracy in performing these analyses, and other characteristics which influence their utility.
