Quick Start

import pandas as pd
import numpy as np
from reliabilipy import reliability_analysis

correlations_matrix = pd.DataFrame(np.matrix([[1., 0.483, 0.34, 0.18, 0.277, 0.257, -0.074, 0.212, 0.226],
                                              [0.483, 1., 0.624, 0.26, 0.433, 0.301, -0.028, 0.362, 0.236],

                                              [-0.074, -0.028, 0.233, 0.165, 0.041, 0.133, 1., 0.346, 0.206],

reliability_report = reliability_analysis(correlations_matrix=correlations_matrix)
reliability_report.fit()
print('here omega Hierarchical: ', reliability_report.omega_hierarchical)

print('here Omega Total', reliability_report.omega_total)
print('here Alpha Cronbach total', reliability_report.alpha_cronbach)

Context

It is common to try check the reliability, i.e.: the consistency of a measure, particular in psychometrics and surveys analysis.

R has packages for this kind of analysis available, such us psychby Revelle (2017). python goes behind on this. The closes are factor-analyser and Pingouin. As I write this there is a gap in the market since none of the above libraries currently implement any omega related reliability measure. Although Pingouin implements Cronbach's alpha

Aim

  1. To bring functions to python for psychometrics and survey analysis, as there is a gap. Mostly from the package in R psych.
  2. To make the ideas and math behind those clear and transparent with examples, and documentation.
  3. To allow people to collaborate and ask questions about.
