Runs a difference in differences analysis in Python.

Project description

Introduction

It's critical to know if the work we are doing is helping the team reach its organizational goals. The problem is that there are potentially many other effects at play. One analysis method for doing this is called a difference in differences analysis. If I had done nothing, then what would have happened to the numbers I care about or "key performance indicators" (KPI) after people started using my product.

It's not always feasible (e.g. due to cost or lack of necessary infrastructure) or ethical (e.g. randomly assigning a cancer-causing drug to a subgroup of the population sample) to run a fully randomized experiment when building a product. If you're looking to measure impact on some quantitative KPIs and you can't run experiments/"randomized control trials"/"AB Testing", then this type of analysis is for you.

Thanks to Sol Sadeghi (Cosine Data Science team @ Microsoft) for informing me about this analysis technique and helping with the initial code review!

Case Study

Example of how this tool was used inside of Microsoft to show the (5+%) impact of a product on internal/"1st party" developer productivity within the Windows division at Microsoft coming soon.

Getting Started

Our documentation is available on this repository's wiki.

Demo

To see a full demonstration of the tool with some example data,

  1. Navigate to the example directory.
  2. Run the following command:
python exampleDIDAnalysis.py
