Sample size calculation for planning group sequential longitudinal trials.

A Liu1, J M Boyett, X Xiong.   

Abstract

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).
