Fitting Linear Mixed-Effects Models using lme4
cran.r-project.org1.1. Linear mixed models Just as a linear model is described by the distribution of a vector-valued random response variable, Y, whose observed value is y obs, a linear mixed model is described by the distribution of two vector-valued random variables: Y, the response, and B, the vector of random effects.
The MIXED Procedure - University of Iowa
homepage.stat.uiowa.eduThe MIXED procedure fits a variety of mixed linear models to data and enables you to use these fitted models to make statistical inferences about the data. A mixed linear model is a generalization of the standard linear model used in the GLM procedure, the generalization being that the data are permitted to exhibit correlation and nonconstant

Introduction to Generalized Linear Mixed Models
site.caes.uga.eduMar 27, 2018 · Like linear mixed models, generalized linear mixed models use maximum likelihood techniques to estimate model parameters. The default estimation technique for proc glimmix is residual pseudo likelihood (RSPL) when the data are non-normal. However, RSPL does not produce a true log-likelihood when modeling non-normal data.
