Abstract
The present model treats the scaling of pair-comparison preference judgments among a unidimensional set of stimuli across a population of individuals. Given a setS ofn stimuli,S = {S 1,S 2, …,S n }, the model yields a partially ordered metric on the interstimulus distances which may be used to construct an interval scale of values forS. Obtained also are a set of predictionsP = {P 1,P 2, …,P n } whereP i is the proportion of individuals in the population whose first choice among the elements ofS isS i . A numerical illustration is offered and comparisons are drawn with Coombs' unfolding technique.
