本文回顾了针对二进制数据提出的许多不同的组内相关性估计器，并在广泛的模拟研究中对它们进行了比较。其中一些估计器是非常具体的，而另一些估计器是由伪似然和扩展拟似然估计等一般方法得出的。模拟研究确定了几个有用的估计器，其中一个似乎以前没有考虑过二进制数据。基于扩展拟似然的估计在某些情况下被发现有很大的偏差。
This paper reviews many different estimators of intraclass correlation that have been proposed for binary data and compares them in an extensive simulation study. Some of the estimators are very specific, while others result from general methods such as pseudo-likelihood and extended quasi-likelihood estimation. The simulation study identifies several useful estimators, one of which does not seem to have been considered previously for binary data. Estimators based on extended quasi-likelihood are found to have a substantial bias in some circumstances.
