Bayesian Modelling in Python. Welcome to "Bayesian Modelling in Python" - a tutorial for those interested in learning how to apply bayesian modelling techniques in python ().This tutorial doesn't aim to be a bayesian statistics tutorial - but rather a programming cookbook for those who understand the fundamental of bayesian statistics and want to learn how to build bayesian models using python. To get a range of estimates, we use Bayesian inference by constructing a model of the situation and then sampling from the posterior to approximate the posterior.

This repository contains some Python demos for the book Bayesian Data Analysis, 3rd ed by Gelman, Carlin, Stern, Dunson, Vehtari, and Rubin (BDA3). Bayesian statistics is an effective tool for solving some inference problems when the available sample is too small for more complex statistical analysis to be applied. Please follow this link for an updated version of the code that have been tested to run with the last version of PyMC3. The book is introductory so no previous statistical knowledge is required, although some experience in using Python and NumPy is expected.
