摘要：本文讨论了所有或大部分观测结果都是定性的情况下的判别问题。Cox（1966）和Day & Kerridge（1967）引入的logistic判别方法被扩展到使用Aitchison & Silvey（1958）关于约束最大似然估计的结果，从每个总体中提取单独样本的情况。该方法进一步推广到三个或更多种群之间的区分。通过仿真研究了logistic判别的性质，并将该方法应用于干燥性角膜结膜炎的鉴别诊断。
SUMMARYThe problem of discrimination when all or most of the observations are qualitative is discussed. The method of logistic discrimination introduced by Cox (1966) and Day & Kerridge (1967) is extended to the situation where separate samples are taken from each population, using the results of Aitchison & Silvey (1958) on constrained maximum likelihood estimation. The method is further extended to discrimination between three or more populations. The properties of logistic discrimination are investigated by simulation and the method is applied to the differential diagnosis ofkerato-conjundivitis sicca.
