Factorial Preference Structures
This article presents a way to model individual preferences and purchase intentions under the assumption that the pattern of relative similarity or substitutability among brands can be represented factorially. Factorial preference structure represent a compromise between the Luce model, which assumes that none of the alternatives share any common features, and EBA, which assumes that each possible subset of a choice set has a unique set of common features. Factorial preference structures are compared to several hierarchical structures and to one that assumes that preferences are simply scalable. Copyright 1990 by the University of Chicago.
