Choice experiments are often used to gather information on preferences of consumers for products and services when the choice alternatives can be described in terms of attributes, each such attribute having two or more settings or, levels. We assume that each attribute has two levels and the interest is to find optimal or efficient designs for estimating the main effects of the attributes and possibly some interactions as well. In this paper we provide such efficient designs for estimating all the main effects and a subset of two-factor interactions among the attributes.
