特异性 (Q)、灵敏度 (Xq) 和预测值 (p) 已被提议作为每种诊断程序在疾病 D 检测中的有效性的衡量标准(例如,Thorner 和 Remein [1961];Vecchio,[1966])。假设可以通过 t 次程序获得关于一系列 n 名患者中每名患者是否存在 D 以及他们的诊断的明确结果。在本文中,针对 7、7 和 p 的同质性开发了 x2 检验。这些利用了作者的匹配样本 x2 结果(Bennett [1967;1968])。
Specificity (Q), senisitivity (Xq) and predictive value (p) have been proposed as measuies of the effectiveness of each of say t diagnostic procedures in the detection of a disease D (e.g., Thorner and Remein [1961]; Vecchio, [1966]). It is assumed that a definitive result can be obtained on the presence or absence of D in each of a series of n patients together with their diagnoses by the t procedures. In this paper x2 tests are developed for homogeneity of 7, 7, and p. These utilize matched sample x2 results of the author (Bennett [1967; 1968]).
