.— A discriminant‐analysis method for dichotomized data, based on the weighted H ‐index as the similarity measure between two persons, is introduced. The weight assigned each item is a strictly increasing function of the absolute value of its D ‐estimate. Here, only power functions are used. The method which is called the WHIDD‐analysis, is applied to some clinical data (Jonsson, 1975). The power of 3 produces a correct classification of all 32 persons in the validation group.
