Books

  1. Andrew Gelman, and Aki Vehtari (2024). Active Statistics. Cambridge University Press. Publisher’s webpage for the book and the home page for the book. This book provides statistics instructors and students with complete classroom material for a one- or two-semester course on applied regression and causal inference. It is built around 52 stories, 52 class-participation activities, 52 hands-on computer demonstrations, and 52 discussion problems that allow instructors and students to explore in a fun way the real-world complexity of the subject. The book fosters an engaging ‘flipped classroom’ environment with a focus on visualization and understanding. The book provides instructors with frameworks for self-study or for structuring the course, along with tips for maintaining student engagement at all levels, and practice exam questions to help guide learning. Designed to accompany the authors’ previous textbook Regression and Other Stories, its modular nature and wealth of material allow this book to be adapted to different courses and texts or be used by learners as a hands-on workbook. Expected publication date March 2024.

  2. Andrew Gelman, Jennifer Hill, and Aki Vehtari (2020). Regression and other stories. Cambridge University Press. Publisher’s webpage for the book and the home page for the book. Back cover text: Many textbooks on regression focus on theory and the simplest of examples. Real statistical problems, however, are complex and subtle. This is not a book about the theory of regression. It is a book about how to use regression to solve real problems of comparison, estimation, prediction, and causal inference. It focuses on practical issues such as sample size and missing data and a wide range of goals and techniques. It jumps right in to methods and computer code you can use fresh out of the box.

[*]Winner of the 2016 De Groot Prize from the International Society for Bayesian Analysis (awarded to the author or authors of an outstanding published book in Statistical Science).
