系数κ通常是根据计算过程而不是总体来定义的。这里提出了人口定义。在此基础上，将 κ 解释为表征个体的诊断可靠性度量，并检查了 κ 测量的可靠性对估计偏差、精确度和测试功效的影响。确定了影响κ大小的因素。提出了提高可靠性的策略，包括组合多个不可靠的诊断。
Coefficientκ is generally defined in terms of procedures of computation rather than in terms of a population. Here a population definition is proposed. On this basis, the interpretation ofκ as a measure of diagnostic reliability in characterizing an individual, and the effect of reliability, as measured byκ, on estimation bias, precision, and test power are examined. Factors influencing the magnitude ofκ are identified. Strategies to improve reliability are proposed, including that of combining multiple unreliable diagnoses.
