Think Bayes

Think Bayes, 2nd Edition, is a textbook by Allen B. Downey, published by O'Reilly Media, that introduces Bayesian statistics through computational methods. Rather than relying on calculus and standard mathematical notation, the book uses Python code to explain statistical concepts.

The volume models probability distributions with discrete approximations, replacing integrals with summations and continuous functions with array operations. Subject areas include Poisson processes, decision analysis, and classification.

Designed for readers with programming knowledge, the text allows learners to apply coding skills to statistical problems. Every chapter features a Jupyter notebook that supports running code and completing exercises locally or via Colab.
