| Abstract: | Several studies have documented the existence of a positive association between the number of levels used for an attribute and the attribute's estimated influence (relative importance) on preference judgments in conjoint analysis. The authors propose that this number-of-levels effects is contingent upon the (lack of) metricity in the preference judgments. They use magnitude estimation to test this idea. They find that rating scale and magnitude estimation data provide comparable average effects. |
