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

翻译：R trippendorffsalpha 软件包提供了使用Krippendorf's Alpha 系数衡量协议的工具,这是一个众所周知的非参数性协议度量(也称为跨河者可靠性和其他名称) 。 本条首先自然地开发了 Krippendorf's Alpha, 并将阿尔法置于统计程序之中。 然后通过分析两个数据集来演示软件包的使用 kirippentorffsalpha, 后者是在对臀部软体进行成像研究时收集的。 软件包允许用户对名义、 交点、 间隔或比率测量水平使用内置距离函数来应用阿尔法方法 。 用户定义的距离功能也得到了支持。 安装功能可以容纳任何数量的单位、 任何编码员和缺失。 支持“ 诱骗陷阱”, 并可以同时进行 。
