Bayesian Statistics is the school of thought that combines prior beliefs with the likelihood of a hypothesis to arrive at posterior beliefs. The first edition of Peter Lee's book appeared in 1989, but the subject has moved ever onwards, with increasing emphasis on Monte Carlo based techniques.
"As a lifelong non-statistician and sporadic "user" of statistics, I have not come across another advanced statistics book (as I would characterize this one) that offers so much to the non-expert and, I'll bet, to the expert as well. The book has my highest recommendation." (Computing Reviews, 7 January 2013)
