"The author has done a wonderful job of selecting the topics and the illustrative examples. The emphasis of the book is less on rigorous mathematical details and more on ideas and practical implementation.This book will be suitable as a text for master’s and Ph.D. students in epidemiology and biostatistics. Researchers interested in learning more about design and analysis of epidemiological studies will find this book useful as well."Kaushik Ghosh, University of Nevada, Las Vegas, U.S.A, Journal of the American Statistical Association, January 2024."Overall, this is a comprehensive book that gives a clear and unified view across many important epidemiological concepts and approaches. The clarity that Reilly has achieved on summarizing and unifying the scattered literature is admirable, and in this sense, the book is a fantastic source of essential information that had earlier been lurking all around in small pieces that were difficult to find."Reijo Sund, University of Eastern Finland, Finland, International Statistical Review, June 2024.
