We develop a statistical model for method comparison studies where a gold standard is present and propose a measure of agreement. This measure can be interpreted as a population correlation coefficient in a constrained bivariate model. An estimator of this coefficient is proposed and its statistical properties explored. Applications of the new methodology to data from the medical literature are presented.
我们为存在金标准的方法比较研究开发了一种统计模型，并提出了一种一致性度量方法。该度量方法可解释为约束双变量模型中的总体相关系数。我们提出了该系数的一个估计量，并探讨了其统计性质。文中展示了新方法在医学文献数据中的应用。
