Abstract: For choice experiments involving pairs of options described by a common set of two-level factors a new method for generating exact designs is presented, which allow the efficient estimation of main effects and first-order interactions. For high efficiencies these designs often require a smaller number of choice sets than available alternatives in the literature.
Keywords: balanced incomplete block design, Hadamard matrix, interactions, optimal design, paired comparisons.
