Time Parameterizations in Cluster Randomized Trial Planning
American Statistician, 2020Models for cluster randomized trials conducted over multiple time periods should account for underlying temporal trends. However, in practice there is often limited knowledge or data available to inform the choice of time parameterization of these trends,

Randomization inference for balanced cluster-randomized trials
Clinical Trials, 2005This paper discusses the choice of randomization tests for inferences from cluster-randomized trials that have been designed to ensure a balanced allocation of clusters to treatments. Methods for covariate-adjusted randomization tests are reviewed and their application to balanced cluster-randomized trials discussed. Two cluster-randomized trials with

Intra‐cluster correlation selection for cluster randomized trials
Statistics in Medicine, 2016In this paper, we give focus to cluster randomized trials, also known as group randomized trials, which randomize clusters, or groups, of subjects to different trial arms, such as intervention or control. Outcomes from subjects within the same cluster tend to exhibit an exchangeable correlation measured by the intra‐cluster correlation coefficient (ICC)
