• The Design of Cluster Randomized Crossover Trials (2011, background): “Equations for calculating optimal allocation of units given budget constraints for other designs can be found in for example Snijders and Bosker (1993), Moerbeek et al. (2000), and Liu (2003).”
• Challenges in Educational Reform: An Experiment on Active Learning in Mathematics (2015, methodology): “Therefore following Liu (2003), the sample size in the cheaper intervention group should be around 33 percent larger.”
• Methods for sample size determination in cluster randomized trials (2015, methodology): “Liu studies the optimal allocation of units to treatment group when the cost per cluster varies across the treatment groups, assuming a mixed model analysis.(60) The optimal cluster allocation ratio depends upon the cost ratio between the treatment and control.”
