Bayesian Decision Analysis

Abstract: 

This workshop is a hands-on introduction to Bayesian Decision Analysis (BDA), which is a framework for using probability to guide decision-making under uncertainty. I start with Bayes's Theorem, which is the foundation of Bayesian statistics, and work toward the Bayesian bandit strategy, which is used for A/B testing, medical tests, and related applications. For each step, I provide a Jupyter notebook where you can run Python code and work on exercises.

Background Knowledge
I assume that you are familiar with Python at an intermediate level. I use NumPy, SciPy, and Pandas, but I explain what you need to know as we go. You should be familiar with basic probability, but you don't need to know anything about Bayesian statistics.
