“References are listed after each chapter … reflecting the wealth of his contribution to the subject of causal inference over the last four decades. … The book is a comprehensive account of methods for comparing treatments in an observational study, rich with detailed illustrations using data for inferences of substance in education, epidemiology, economics and clinical medicine. … this is an absolute `must' for reading and reference for every statistician who works with observational studies … .” (Nicholas T.
