Hello, have a look at these slides by Douglas Bates on mixed effects models: http://lme4.r-forge.r-project.org/slides/ e.g. http://lme4.r-forge.r-project.org/slides/2009-07-07-Rennes/4Theory-4.pdf perhaps you might find them useful.

When using the ranef function I can extract the random effect coefficients from the model. What I would like to know is how these are estimated. What is the algebra involved in getting these estimates? Thank you very much. Cheers, Cornelia
