本文内容包括:
- 基于生存资料的DCA分析(目前为止尚无成熟的软件包可用)
- MSKCC提供的源函数(搬运工,应用这个函数,并翻译该函数的参数)
- 示例展示多因素cox模型的DCA分析,以lung数据集为例
- 示例展示单因素cox模型的DCA分析,分别以melanoma, lung两个数据集展示
- 绘制net reduction in interventions随阈概率变化的关系
广而告之
说一个事,鉴于简书平台在信息传播方面有不足之处,应粉丝要求,白介素2的个人微信平台已经开启,继续聊临床与科研的故事,R语言,数据挖掘,文献阅读等内容。当然也不要期望过高,微信平台目前的定位是作为自己的读书笔记,如果对大家有帮助最好。如果感兴趣, 可以扫码关注下。

决策曲线分析
-
决策曲线分析是评估预测模型,诊断测试和分子标记的简单方法。
-
该方法首次在2006年由MSKCC的 Vickers AJ博士发表在 Medical Decision Making杂志上,Vickers AJ, Elkin EB. Decision curve analysis: a novel method for evaluating prediction models. Medical Decision Making. 2006 Nov-Dec;26(6):565-74.,相对于ROC曲线还是比较年轻的一种方法.
-
2008年又进一步在该杂志上详细描述了该方法: Steyerberg EW, Vickers AJ. Decision curve analysis: a discussion. Medical Decision Making. 2008 Jan-Feb;28(1):146-9.
-
2008年11月,Vickers AJ又进一步扩展了 DCA的应用范围,推广到了生存资料的分析,用于评估诊断试验,分子标志,预测模型:Vickers AJ, Cronin AM, Elkin EB, Gonen M. BMC Medical Informatics and Decision Making. 2008 Nov 26;8(1):53. Extensions to decision curve analysis, a novel method for evaluating diagnostic tests, prediction models and molecular markers.
