Decision theory for selecting the winners, ranking and classification
N. T. Longford

Abstract

We address the problem of selecting the best of a set of units based on a criterion variable, when its value is recorded for every unit subject to estimation, measurement, or another source of error. The solution is constructed in a decision-theoretical framework, incorporating the consequences (ramifications) of the two kinds of error that can be committed. The related problems of classifying the units to a small number of groups and ranking them are solved by a similar approach. An application is presented to the rates of satisfactory outcomes in the undergraduate courses of a university.
