pylift

Read our documentation!

pylift is an uplift library that provides, primarily:

1. Fast uplift modeling implementations.
2. Evaluation tools (UpliftEval class).

While other packages and more exact methods exist to model uplift, pylift is designed to be quick, flexible, and effective. pylift heavily leverages the optimizations of other packages -- namely, xgboost, sklearn, pandas, matplotlib, numpy, and scipy. The primary method currently implemented is the Transformed Outcome proxy method (Athey 2015).

This branch is a fork from github.com/wayfair/pylift, and is actively being maintained.

Installation

The latest version of pylift can be installed through pypi:

pip install pylift
