Use of mixed effects models for the analysis of longitudinal data, with an emphasis on applications on biostatistics.

This paper should be of interest to students who want to know more about biostatistics and longitudinal analysis.

Mixed models are a powerful class of models used for the analysis of correlated data. Examples of correlated data include, but are not limited to, clustered data, repeated observations, longitudinal data, multiple dependent variables, spatial data or data from population pharmacokinetic/pharmacodynamic studies. A key feature of mixed models is that, by introducing random effects in addition to fixed effects, they allow you to address multiple source of variation, e.g. in the longitudinal study they allow you to take into account both within- and between- subject variations.
