Sample Size Determination for GEE Analyses of Stepped Wedge Cluster Randomized Trials

In stepped wedge cluster randomized trials, intact clusters of individuals switch from control to intervention from a randomly assigned period onwards. Such trials are becoming increasingly popular in health services research. When a closed cohort is recruited from each cluster for longitudinal foll...
