决策曲线分析

决策曲线分析（Decision Curve Analysis，DCA）是Memorial Sloan Kettering Cancer Center的Andrew Vickers博士（vickersa@mskcc.org）等人2006年研究出另一种新的评价方法（传统方法是二战时期诞生的ROC曲线）,它是用来评价预测模型、诊断测试和分子标记的一种简单直观的方法。

Unlike traditional biostatistical techniques, it can provide information as to a test's clinical value, but unlike traditional decision analytic techniques, it does not require patient preferences or formal estimation of the health value of various health outcomes: Only a general clinical estimate is required.
