Heckman两阶段模型：选择偏倚强大校正工具，原理及实现方法

Heckman两阶段模型适用于解决由样本选择偏差（sample selection bias）造成的内生性问题。在经济学领域，样本选择偏差的典型例子是研究女性的受教育情况对女性工资的影响。按照这个思路

临床研究中的混杂偏倚（上）

为什么要讲偏倚？因为在现实临床研究中有太多的因素干扰，如治疗方法不同、患者的一般情况有别、医生与患者个人意愿不同、经济条件影响诊疗方法、民族背景与生活习惯对疾病的影响等等。控制这些偏倚，呈现真实的信息，是临床研究的关键所在。不控制偏倚的研究，都是耍流氓！本文为混杂偏倚上集，相关课程可到MedSci临床研究学院观看。手机下载MedSci医学APP,看视频只需一半积分，一起来学习吧。期待下集更精彩
