The use of random effects models to allow for clustering in individually randomized trialsKatherine J Lee
MRC Biostatistics Unit, Institute of Public Health, Cambridge, UK
Clin Trials 2:163-73. 2005..We propose random effects models to allow for such clustering, across a range of contexts and trial designs, and investigate their effect on estimation and interpretation of the treatment effect...
Flexible parametric models for random-effects distributionsKatherine J Lee
MRC Biostatistics Unit, Institute of Public Health, Robinson Way, Cambridge CB2 0SR, UK
Stat Med 27:418-34. 2008..We conclude that inferences regarding the random effects can crucially depend on the assumptions made and recommend using a distribution, such as those suggested here, which is more flexible than the normal...
