确定在临床环境中获得的评分者间测量结果不存在测量误差并反映真实评分的愿望已经摒弃了对可靠性评估的新兴趣。Kappa系数被认为是分析由多名临床医生记录的同一患者的标称和分类类型数据的可靠性的统计选择。本文介绍了一个简单的计算机程序编写的PASCAL，可用于在临床环境中快速确定名义或分类数据的可靠性。该计算机程序计算加权和非加权kappa系数及其相应的标准误，以及用于小样本量的kappa偏差校正刀切估计。
The desire to determine the extent inter-rater measurements obtained in a clinical setting are free from measurement error and reflect true scores has spurned a renewed interest in assessment of reliability. The kappa coefficient is considered the statistic of choice to analyze the reliability of nominal and categorical types of data recorded on the same patient by more than one clinician. This paper presents a simple computer program written in PASCAL that can be used in a clinical environment to quickly determine the reliability of nominal or categorical data. This computer program calculates both weighted and non-weighted kappa coefficients with their corresponding standard errors as well as bias-correcting jackknife estimates of kappa for use with small sample sizes.
