Abstract

This study presents a novel approach for the confidence interval estimation of a common intraclass correlation coefficient derived from several samples under unequal family sizes. This approach is developed using the concept of generalized pivots. Comparisons are made with a large sample procedure on the coverage probabilities.

摘要

本研究提出了一种新方法，用于在家庭规模不等的情况下，对来自多个样本的常见组内相关系数进行置信区间估计。该方法是利用广义枢轴的概念开发的。在覆盖概率方面与大样本程序进行了比较。
