Decision consistency (DC) is the reliability of a classification decision based on a test score. In professional credentialing, the decision is often a high-stakes pass/fail decision. The current methods for estimating DC are computationally complex. The purpose of this research is to provide a computationally and conceptually simple method for estimating DC that produces results comparable to, and at times potentially better than, the widely used Livingston-Lewis method.

一种估计决策一致性的计算简单方法

决策一致性 (DC) 是基于测试分数的分类决策的可靠性。在专业资格认证中，该决定通常是一个高风险的通过/失败决定。当前用于估计 DC 的方法在计算上很复杂。本研究的目的是提供一种计算和概念上简单的方法来估计 DC，该方法产生的结果可与广泛使用的 Livingston-Lewis 方法相媲美，有时甚至可能更好。
