聚类排列检验是对相关数据进行显著性检验的一种非参数方法。它通常用于群集随机试验，其中患者组而不是个体被随机分配到治疗或对照干预。我们描述了一个灵活而高效的SAS宏，实现了2-样本聚类排列测试。我们讨论了这个测试背后的理论和应用以及SAS代码的细节。
The clustered permutation test is a nonparametric method of significance testing for correlated data. It is often used in cluster randomized trials where groups of patients rather than individuals are randomized to either a treatment or control intervention. We describe a flexible and efficient SAS macro that implements the 2-sample clustered permutation test. We discuss the theory and applications behind this test as well as details of the SAS code.
