Fast Krippendorff

Fast computation of Krippendorff's alpha agreement measure.

Based on Thomas Grill implementation.

Example usage

Given a reliability data matrix, run:

import krippendorff

krippendorff.alpha(reliability_data=...)

See sample.py and alpha's docstring for more details.

Installation

pip install krippendorff

Caveats

The implementation is fast as it doesn't do a nested loop for the coders. However, V should be small, since a VxV matrix it's used.
