This new edition of Medical Statistics at a Glance: bull; bull;contains a second colour throughout to enhance the visual appeal bull;presents the key facts accompanied, where appropriate, by clear and informative tables and diagrams bull;features worked examples in each chapter, with emphasis on the interpretation of computer data analysis rather than on complex hand calculations bull;includes new chapters entitled Rates and Poisson regression, Generalized linear models, Explanatory variables in statistical models and Regression models for clustered data bull;has an accompanying website http://www.medstatsaag.com/ containing supplementary material including an extensive reference list and multiple choice questions (MCQs) with interactive answers for self-assessment. Medical Statistics at a Glance will appeal to all medical students, junior doctors and researchers in biomedical and pharmaceutical disciplines. Reviews of the last edition ls"All in all, this is a book that I would highly recommend to the target audience. Concise, accurate, broad coverage, in an easy-to-use formathellip; buy this and you will have the best set of lecture notes in the class!rs" The Statistician, 2001 ls"The more familiar I have become with this book, the more I appreciate the clear presentation and unthreatening prose.rs" Journal of Epidemiology ls"...I unreservedly recommend this book to all medical students, especially those that dislike reading reams of text. This is one book that will not sit on your shelf collecting dust once you have graduated and will also function as a reference book.rs" 4th year medical student, Barts and the London Chronicle, Spring 2003 "an excellent job of making medical statistics as relevant and painless as it possibly could behellip;if statistics give you headaches buy it" GKT Gazette "It is now a valuable companion to my statistics course" International Journal of Epidemiology "As one who generally has not got a clue whenit comes to statistics, this is a book I would definitely recommend" Surgo: Glasgow University Medical Journal "This bookhellip;was actually enjoyable to read" Cambridge Medicine "Nothing is too obscure, there are lots of worked examples, and clear diagrams.
