Coefficients to measure inequality.
This is small library with some implemented coefficients (or indices) intended to measure inequality or concentration of the values in a population.
- Gini Coefficient
- Ratio top / rest
This library is hosted on PyPI, so installation is straightforward. The easiest way to install type this at the command line (Linux, Mac, or Windows):
pip install inequality_coefficients
This library also depends on numpy, but
pip should take of that for
For the simplest, typical use cases, this tells you everything you need to know.:
import inequality_coefficients as ineq data = array([1.7, 3.2 ...]) # data can be list of nums or numpy array gini_coeff = ineq.gini_coeff(data) ratio_top_rest = ineq.ratio_top10_rest(data)
Many thanks to Felipe Ortega to open source his implementation of the Gini coefficient, available here: https://github.com/ryanwitt/wikixray/blob/master/graphics.py.
My code is based on that implementation, although I have made some changes and added a correction for small datasets based on Deltas, 2003.
