PyMC Examples

Supporting examples and tutorials for PyMC, the Python package for Bayesian statistical modeling and Probabilistic Machine Learning!

Check out the getting started guide, or interact with live examples using Binder! Each notebook in PyMC examples gallery has a binder badge. For questions on PyMC, head on over to our PyMC Discourse forum.

Getting started

If you already know about Bayesian statistics:

• API quickstart guide
• The PyMC tutorial
• PyMC examples and the API reference

Learn Bayesian statistics with a book together with PyMC:

• Probabilistic Programming and Bayesian Methods for Hackers by Cameron Davidson-Pilon: Fantastic book with many applied code examples.
• Doing Bayesian Data Analysis by John Kruschke, as well as the second edition: Principled introduction to Bayesian data analysis.
• Statistical Rethinking: A Bayesian Course with Examples in R and Stan by Richard McElreath: Comprehensive text on modeling choices and interpretations.
• Bayesian Cognitive Modeling by Michael Lee and EJ Wagenmakers: Focused on using Bayesian statistics in cognitive modeling.
• Bayesian Analysis with Python (second edition) by Osvaldo Martin: Great introductory book. (code and errata).

PyMC talks

There are also several talks on PyMC, which are gathered in this YouTube playlist and as part of PyMCon 2020
