Published in 1939, this book was the first to develop a fundamental theory of scientific inference based on the ideas of Bayesian statistics. Recent advances in computer power and availability have brought Bayesian statistics into the limelight and make this book a must for all serious statisticians.
`Its selection as an Oxford Classic Text is unusual but well judged: unusual, for the book has had no impact on how most scientists do statistics, and prescient because Bayesian methods are now gaining wider acceptance - at least among more mathematically competent researchers. Those who don't have to rush to the bathroom when they see an integral sign can hardly fail to benefit from reading this book.' Robert Matthews in New Scientist
