A review on linear mixed models for longitudinal data, possibly subject to dropoutBiostatistics, Limburgs Universitair Centrum, Universitaire Campus, Diepenbeek, The Netherlands, geert.molenberghs{at}luc.ac.be
Biostatistical Centre, Catholic University of Leuven, UZ St.-Rafaël, Leuven, The Netherlands Many approaches are available for the analysis of continuous longitudinal data. Over the last couple of decades, a lot of emphasis has been put on the linear mixed model. The current paper is dedicated to an overview of this approach, with emphasis on model formulation, interpretation and inference. Advantages as well as drawbacks are discussed, and guidelines are given for general statistical practice. Special attention is given to the problem of missing data, i.e., the case where not all data are present as planned in the original design of the study.
Key Words: dropout linear mixed models longitudinal data missing data pattern mixture model random effects selection model
