Adaptive Design Theory and Implementation Using SAS and R

"Rigidly adhering to frequentist principles can only take one so far. Mark Chang dedicates his marvellous tome to ‘those who are striving toward a better way’; this book is an ideal vessel with which to begin."—International Society for Clinical Biostatistics, 2017"... this text is a compilation of numerous adaptive trial designs that have been developed over the past few decades, including interim analyses, sample size re-estimation, biomarker enrichment, and response-adaptive treatment assignment. It is also an update to the first edition published in 2008 and includes 12 new chapters, as well as reformulations of several other chapters. ... Two strengths of this text are the numerous examples that are included throughout and the inclusion of open-ended problems at the end of chapters to help readers work through some of the concepts on their own. Another strength of this text is its attempt to cover as many adaptive designs as possible. ... This text is certainly a useful reference that covers approaches to adaptive clinical trial design, but would only be suitable for those with sufficient graduate-level statistical training and background in clinical trial design and programming."—Thomas M. Braun, Department of Biostatistics, University of Michigan, writing in International Statistical Review, (2015), 83, 3, 511-522Praise for the First Edition:"The SAS and R programs are available on the web. This is good news since it avoids painful re-typing and error checking. … The book can provide all statisticians interested in the adaptive design field with an overview of the topic and software to run practical examples."—Pharmaceutical Statistics, 2011, 10"… this book covers many of the different forms of adaptive design. … The book also provides both SAS and R code to implement the theory, making the implementation of the theory much more accessible to readers. … Its strength is that it provides an overview on many different types of adaptive designs, with an excellent source of references. … a useful resource in this relatively new and quickly developing field."—Patrick Kelly, Statistics in Medicine, Vol. 29, 2010"This book provides a thorough overview of adaptive designs in clinical trials similar to another book on adaptive designs coauthored by Dr. Chang (Chow and Chang, 2006), but using a more theoretical framework. … this book is an excellent addition to the biostatistics book series … . It provides a comprehensive summary of adaptive designs that have been developed, and includes about 400 references in the bibliography. The general theory behind most of the adaptive designs is helpful in understanding their advantages over fixed designs, as well as their potential pitfalls. The SAS and R programs associated with each adaptive design make the book practical as well."—Journal of the American Statistical Association, Vol. 104, No. 487, September 2009"… this book provides a systematic introduction to adaptive design theory. It also gives trial examples and computing code to help readers construct a comprehensive understanding of adaptive designs. It is certainly a useful guide and reference for academic and industry statisticians alike."—Feifang Hu, Biometrics, June 2009"This easy-to-read book provides the reader with a unified and concise presentation of adaptive design theories, together with computer programs written in SAS and R for the design and simulation of adaptive trials. … The text, computer programs, and data sets will be of value to both practitioners and students alike."—International Statistical Review, 2008
