From a review of the previous edition "This closely written but readable presentation of advanced methods increasingly used in the medical literature uses clinical examples to give meaning to these statistical methods. The experienced author reports the essence of statistical methods with only minimal use of mathematical notation. Underlying concepts are well described in the introductory chapter and in appendices, and the statistical references are excellent. Cautions on the misuse of methods abound. Useful guidance on presentation of methods and results appears in each chapter. Brief presentations of this quality are rare." Annals of Internal Medicine, December 2001 About SS1 & SS2 "These two books are quite amazing. The depth and detail contained in these two tiny volumes is quite stunning. The way the two books have been written is succinct, and yet, does allow the student to understand the way the material is presented." Senior Lecturer, Tissue Viability Unit
