Fitting Linear Mixed-Effects Models using lme4

cran.r-project.org

paper we describe the formulation and representation of linear mixed models. The techniques used for generalized linear and nonlinear mixed models will be described separately, in a future paper. At present, the main alternative to lme4 for mixed modeling in R is the nlme package (Pin-heiro, Bates, DebRoy, Sarkar, and R Core Team 2014).
