倾向性评分方法可以用多种方式进行,不同的方式产生不同的目标人群,两种常用的倾向性评分方法是倾向评分匹配(propensity score matching,PSM)和倾向分数加权(propensity score weighting,PSW)。 倾向评分匹配: 倾向评分匹配是使用最广泛的一种倾向性评分方法。而在倾向性评分匹配中,又以1:1近邻匹配被使用最广泛。 在观...
我们可以定义Propensity score: 抽烟e(x)=defPr(treatment=抽烟|X=x). 现在如果有两个人,一个抽样,一个不抽烟,但是他们的Propensity score是一样的(或者相似的),我就将他们分别分到抽烟组和不抽烟组,只要找到足够多这样的pair,这两个分组就会跟协变量独立。更直观来说,两个人的Propensity score一样,意味着他...
We propose a simple way of improving estimators of treatment eff ects that are based on propensity score weighting. As the weights are arbitrarily large when the propensity scores are close to one or zero, we propose to shrink the propensity scores away from these boundaries. This simple method...
This is the key assumption that makes inverse propensity score weighting "work." Third, using the definition e(Xi):=E(Di|Xi=x)e(Xi):=E(Di|Xi=x) we can rewrite the numerator as E(Yi(1)|Xi=x)e(Xi)E(Yi(1)|Xi=x)e(Xi) and similarly for the second fraction. This gives us E...
这说明，存在一个可能的协变量，如“喜欢抽烟”，导致了选择干预方式的不同。为了解决这个问题，我们可以使用倾向评分（Propensity Score）。倾向评分是通过寻找一种分组方式，使得协变量与干预方式独立。具体来说，我们可以通过计算每个个体的倾向评分，即得到该个体被分配到某一干预组的概率，以此来匹配相似...
