Mixed models with medical and engineering applications

A useful reference regarding practical aspects of fitting mixed models in R is Faraway, J.J. (2006) Extending the linear model with R, Chapman and Hall/CRC, chapter 2 and 8.

Details on fitting linear mixed models in SPSS are provided in these notes.
