etacorpy 0.1.4

A Python package for calculating eta n, the rank-transform area coverage coefficient of correlation.

etacorpy

A Python package for calculating eta_n, the rank-transform area coverage coefficient of correlation. This is the official repository of the paper (link TBD):

"A coefficient of correlation for continuous random variables based on area coverage"

Installation

Install this library using pip:

pip install etacorpy

Usage

import numpy as np
from etacorpy import calc_eta_n
x = np.random.rand(100)
y = np.random.rand(100)
print(f'x and y are independent, eta_n = {calc_eta_n(x,y)}')
y = np.square(x)
print(f'x and y are dependent, eta_n = {calc_eta_n(x,y)}')

Development

To contribute to this library, first checkout the code. Then create a new virtual environment:

cd etacorpy
python -m venv venv
source venv/bin/activate

Now install the dependencies and test dependencies:

python -m pip install -e '.[test]'

To run the tests:

python -m pytest
