Procedures are developed in this paper for sample size calculations for planning a group sequential longitudinal trial with various correlation structures, using a test statistic based on generalized estimating equations (Lee, Kim and Tsiatis) and group sequential boundaries based on type I error spending functions (Lan and DeMets).
本文开发了一些程序，用于计算样本量，以便规划具有各种相关结构的成组序贯纵向试验，使用基于广义估计方程（Lee、Kim和Tsiatis）的检验统计量以及基于I型错误消耗函数（Lan和DeMets）的成组序贯界值。
