在前面的统计学注释1中，我们评论了配对数据的分析，其中每个受试者有多个观察结果，如表I所示。我们指出，将几个受试者的重复观察结果结合起来，然后计算相关系数，就好像这些数据是一个简单的样本，这样分析这些数据可能会产生很大的误导。本说明是对几封关于对这些数据进行适当分析的信件的答复。
In an earlier Statistics Note 1 we commented on the analysis of paired data where there is more than one observation per subject, as shown in table I. We pointed out that it could be highly misleading to analyse such data by combining repeated observations from several subjects and then calculating the correlation coefficient as if the data were a simple sample. This note is a response to several letters about the appropriate analysis for such data.
