Given that there are, arguably, two primary approaches to statistics, frequentist (or classical) and Bayesian, most of the textbooks are written by frequentist statisticians. However, more and more people have realized the advantages of using Bayesian statistics and they have appeared increasingly in forensics and other areas of analysis. Bolstad’s book focuses on Bayesian statistics as a textbook for undergraduate students as well as useful material for anyone with an interest in the subject.
