R package krippendorffsalpha provides tools for measuring agreement using\nKrippendorff's Alpha coefficient, a well-known nonparametric measure of\nagreement (also called inter-rater reliability and various other names). This\narticle first develops Krippendorff's Alpha in a natural way, and situates\nAlpha among statistical procedures. Then the usage of package\nkrippendorffsalpha is illustrated via analyses of two datasets, the latter of\nwhich was collected during an imaging study of hip cartilage. The package\npermits users to apply the Alpha methodology using built-in distance functions\nfor the nominal, ordinal, interval, or ratio levels of measurement.\nUser-defined distance functions are also supported. The fitting function can\naccommodate any number of units, any number of coders, and missingness.\nBootstrap inference is supported, and the bootstrap computation can be carried\nout in parallel.\n
