"…a valuable mixed model resource for most applied statisticians working in the medical environment." (Biometrics, June 2007) "…useful for practitioners and applied statisticians working in medical science." (Journal of the American Statistical Association, September 2007)"…takes a practical rather than theoretical approach and requires understanding of only basic statistics." (MAA Reviews, October 30, 2006)“This second edition gives an overview of the theory of mixed models and its application to real data in medical research.” (Zentralblatt MATH, April 2007)
