  "Description": "Calculates and compares various reliability coefficients\nfor unidimensional and multidimensional scales. Supported\nunidimensional estimators include coefficient alpha, congeneric\nreliability, the Gilmer-Feldt coefficient, Feldt's classical\ncongeneric reliability, Hancock's H, Heise-Bohrnstedt's omega,\nKaiser-Caffrey's alpha, and Ten Berge and Zegers' mu series.\nMultidimensional estimators include stratified alpha, maximal\nreliability, correlated factors reliability, second-order\nfactor reliability, and bifactor reliability.
