类内相关系数(Intraclass Correlation Coefficient, ICC)是一种用于评估不同评估者对同一组数据的评分一致性或可靠性的统计指标。它常用于临床研究、心理学、教育等领域,特别是在需要多次测量或不同评估者评分的情况下。ICC值的范围在0到1之间,越接近1表示一致性越高。 ICC的理解 1、ICC的解释: ICC = 0:表示没...

The intraclass correlation is VB/(VB + VW), where VB is between-cluster and VW within-cluster variance. One way to handle the test of the icc being the same across time is to use parameter labels in Model and then use Model Constraint: Model: %Within% y1-y2 (vw1-vw2); %be...
