How compare two products on Amazon using a Bayesian analysis

How a Bayesian Shops on Amazon

This notebook uses Bayesian analysis to determine the probability that one product is better than another.

Motivation

The reason I chose to publish this notebook is three-fold:

1. I wanted to tackle a problem that used the multinomial and dirichlet distributions rather than the typical binomial with a beta prior
2. I hoped to show that Bayesian analysis can be used to solve very practical problems and give intuitive results
3. I wanted to help people who are familiar with the basics of Bayes' Rule and probability extend the concept for use with distributions and relative likelihoods

Run with Docker on your machine (must have Docker installed)

1. git clone https://github.com/exchez/amazon-bayes.git
2. cd amazon-bayes
3. docker-compose up
4. make sure to run docker-compose down when you're done

Run on Binder

1. Click the link to binder above
2. Get up and grab a coffee (optional). It may take ~15 minutes to build the image if it's not cached.
3. Replace "tree" at the end of the url with "lab" to run in Jupyter Lab (optional). Though I actually think it looks nicer in a notebook.
