开发了两个相关类内相关系数（ICCs）之间差异的四个置信区间，重点是应用于家庭研究。这里采用的基本思想是，两个参数之差的置信区间可以从每个参数的置信限中得到。在考虑的四种置信度方法中，对单个ICC基于逆双曲正切变换的置信度方法效果最好。弗朗西斯·高尔顿（Francis Galton）关于人类身高的数据被用来说明这种方法。
Four confidence intervals for a difference between two dependent intraclass correlation coefficients (ICCs) are developed, focusing on applications to family studies. The basic idea adopted here is that confidence intervals for a difference between two parameters can be obtained from confidence limits for each parameter. Among the four confidence procedures considered, the one based on the inverse hyperbolic tangent transformation for a single ICC performed best. Francis Galton's data on human stature are used to illustrate the methodology.
