“I would be happy to recommend this nice handy book as a reference to my students. The clarity of the writing and proper choices of examples allows the presentations of many statistical methods shine.” (The American Statistician, 1 February 2015)“Overall, a valuable user-friendly resource. Summing Up: Highly recommended. Upper-division undergraduates through professionals.”  (Choice, 1 October 2013)“All in all, I also very much like the Handbook and if I were not to retire this year, I would be happy to tell my students that it is a very nice and handy book.”  (International Statistical Review, 15 February 2013)
