pycorr 0.1.5

Python package for calculating correlation amongst categorical variables

PyCorr

A simple library to calculate correlation between variables. Currently provides correlation between nominal variables.

Based on statistical methodology like Cramer'V and Tschuprow'T allows to gauge the correlation between categorical variables. Ability to plot the correlation in form of heatmap is also provided.

Usage example

import pandas as pd
from pycorrcat.pycorrcat import plot_corr, corr_matrix

df = pd.DataFrame([('a', 'b'), ('a', 'd'), ('c', 'b'), ('e', 'd')],
                  columns=['dogs', 'cats'])

correlation_matrix = corr_matrix(data, ['dogs', 'cats'])
plot_corr(df, ['dogs','cats'] )

Development setup

• pip install -r requirements.dev.txt
• pip install -r requirements.txt Then install the pre-commit hooks: pre-commit install and continue with code change.

Run pre-commit locally to check files

pre-commit run --all-files
