Abba: A/B test analysis in Javascript and Python

Abba is a library for A/B test analysis. It analyzes tests with binomial outcomes for any number of groups. You can use the Javascript library (in abba/) to just compute statistics or to render a nice table summarizing those statistics. There's a handy little app in demo/ which demonstrates how to use the library. There's a Python version under python/, also available on PyPI.

You can find a usable app and detailed documentation on the live demo.
