Pw. Henderson et B. Buchanan, A RELATIVELY UNBIASED MEASURE OF DISCRIMINATION ABILITY IN PRODUCT DESIGN - AN ADDENDUM TO BUCHANAN AND HENDERSON (1992), Marketing science, 14(2), 1995, pp. 250-252
In this addendum, we present a measure of discrimination ability that
is free of the downwardly biasing assumptions of previous discriminati
on measures. We discuss the magnitude of the bias in the previous meas
ures, the reliability of all of the measures, intercorrelations among
them, and their appropriate uses.
