"I think this text makes a strong case for the increasing importance of formal (and potentially quantitative) B-R assessment … readers new to B-R will get a well-rounded perspective of the key considerations and challenges to performing these assessments from thorough discussion of the overarching principles, different perspectives, and work to date. The authors identify several gaps, such as the emerging need to include patient perspective into the equation, and acknowledge that there are no universally accepted statistical methods at this time. Whether you are completely new to B-R or whether you are trying to implement quantitative methods at the company or project level, this book will be useful for statisticians charged with supporting these assessments now and in the future."—Pharmaceutical Statistics, 2014
