Python implementation of the R package IRR, all credit goes to the original authors [1]. The package contains functions to calculate coefficients of Interrater Reliability and Agreement for interval, ordinal and nominal data: intraclass-correlations, Finn-Coefficient, Robinson’s A, Kendall’s W, Cohen’s Kappa, and others. This is a straight line-for-line port from the R-package, so it is not particularly Pythonic and mainly made as an exercise to learn more about R. For documentation I highly recommend you head over to the R package page, they put in a lot of effort for the documentation!
How to install
The package is available on the Python Package Index (PyPI). To install it you can run:
pip install pyirr
How to use
A simple example:
from pyirr import read_data, intraclass_correlation
data = read_data("anxiety") # loads example data
intraclass_correlation(data, "twoway", "agreement")
Returns:
==================================================
Intraclass Correlation Results
==================================================
Model: twoway
Type: agreement
Subjects = 20
Raters = 3
ICC(A,1) = 0.20
F-Test, H0: r0 = 0 ; H1 : r0 > 0
F(19.00,39.75) = 1.83, p = 0.0543
95%-Confidence Interval for ICC Population Values:
-0.039 < ICC < 0.494
==================================================
Another simple example:
from pyirr import read_data, kappam_fleiss
data = read_data("anxiety") # loads example data
kappam_fleiss(data, detail=True)
Returns:
==================================================
Fleiss` Kappa for m Raters
==================================================
Subjects = 30
Raters = 6
Kappa = 0.430
z = 17.652
p-value = 0.000
Kappa z p.value
1. Depression 0.245 5.192 0.0
2. Personality Disorder 0.245 5.192 0.0
3. Schizophrenia 0.520 11.031 0.0
4. Neurosis 0.471 9.994 0.0
5. Other 0.566 12.009 0.0
