Title

A measurement of multi-factor orthogonality

Abstract

Orthogonality has been considered as an important design priority in the design literature. This article provides a set of criteria to measure "how orthogonal" a design may be when it is not perfectly orthogonal. These criteria can be obviously applied to a wide variety of designs. Properties of these criteria are discussed, using some existing supersaturated designs as examples.
