An excellent introduction to Bayesian statistical theory.-Frank Windmeijer, Times Higher Education Supplement
This book is a classic.... The strengths of this text are twofold. First, it gives a general and well-motivated introduction to the principles of Bayesian decision theory that should be accessible to anyone with a good mathematical statistics background. Second, it provides a good introduction to Bayesian inference in general with particular emphasis on the use of subjective information to choose prior distributions.-Mark J. Schervish , Journal of the American Statistical Association
This is the authoritative introductory treatise (almost 900 pages) on applied Bayesian statistical theory. It is self-contained and well-presented, developed with great care and obvious affection by the founders of the subject.-James M. Dickey, Mathematical Reviews
