jucor/krippendorff: "Fast Krippendorff Alpha Reliability Measure"

krippendorff computes Krippendorff Alpha for reliability analysis, in a space-efficient manner especially suited for studies where each observer only grades a small fraction of a large number of observations. It provides both Krippendorff's alpha and its bootstrapping evaluation. This implementation is faster and more space-efficient than the more versatile `irr.kripp.alpha` package which offers several other reliability measures but requires the full observation matrix.
