这份简短的说明评估了置换检验所需的假设，以近似库克等人提出的删失结果的空间扫描统计量的零分布。(2007)。特别地，我们研究了在生存模型下进行这种检验所需的互换条件。进一步执行模拟研究，以评估当违反全局可交换性假设时对类型I误差的影响，并确定置换测试是否仍然很好地逼近零分布。
This short note evaluates the assumptions required for a permutation test to approximate the null distribution of the spatial scan statistic for censored outcomes proposed in Cook et al. (2007). In particular, we study the exchangeability conditions required for such a test under survival models. A simulation study is further performed to assess the impact on the type I error when the global exchangeability assumption is violated and to determine whether the permutation test still well approximates the null distribution.
