Data Science

A complete foundation for Statistics, also serving as a foundation for Data Science. Leanpub revenue supports OpenIntro (US-based nonprofit) so we can provide free desk copies to teachers interested in using OpenIntro Statistics in the classroom and expand the project to support free textbooks in other subjects. More resources: openintro.org.

The book is also available in paperback for $25. Paperback royalties go to OpenIntro (US-based nonprofit), and the optional Leanpub PDF contributions go to authors to fund their time on this book.

Your company's answers are already written down. This book builds the machine that finds them.

Everything you really need to know in Machine Learning in a hundred pages.

This book teaches you how to make machine learning models more interpretable.

Master language models through mathematics, illustrations, and code―and build your own from scratch!

Introduction to Statistics for the Life and Biomedical Sciences is the 4th official OpenIntro book and has been written to be used in conjunction with a set of self-paced learning labs. These labs guide students through learning how to apply statistical ideas and concepts discussed in the text with the R computing language.

Includes Editions 1, 2, 3, and 4. Editions 1-3 are listed under "Extras" after checking out, including for $0 purchases. AHSS provides a thorough intro to statistics and supports students preparing for the AP Statistics exam. B&W paperbacks (color) are sold for $25 ($40). Paperback royalties are shared between OpenIntro and the authors. Leanpub contributions go to authors to fund their time.

AI for Data Visualisation shows how large language models (LLMs) can be used to explore, transform and visualise your data. It shows how to use simple prompts to analyse and transform data and to create charts, maps and simple dashboards.

It's never been easier to build an AI agent — and never been harder to make one that actually works. This book takes you from language model foundations to production-ready multi-agent systems with the depth to predict failure before it happens, engineer graceful degradation over catastrophic failure, and take absolute architectural ownership.

The demand for skilled data science practitioners in industry, academia, and government is rapidly growing. This book introduces concepts from probability, statistical inference, linear regression and machine learning and R programming skills. Throughout the book we demonstrate how these can help you tackle real-world data analysis challenges.

This book brings the fundamentals of R programming to you, using the same material developed as part of the industry-leading Johns Hopkins Data Science Specialization. The skills taught in this book will lay the foundation for you to begin your journey learning data science. Printed copies of this book are available through Lulu.

Data analysis is now part of practically every research project in the life sciences. In this book we use data and computer code to teach the necessary statistical concepts and programming skills to become a data analyst. Instead of showing theory first and then applying it to toy examples, we start with actual applications and describe the theory as it becomes necessary to solve specific challenges. The book includes links to computer code that readers can use to follow along as they program.
