Python package for calculating correlation amongst categorical variables
Project description
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
Create a virtualenv and install dependencies:
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
