2.倾向性评分加权法(propensity score weighting,PSW): 逆处理概率加权法( Inverse Probability of Treatment Weighting Using the Propensity Score,IPTW):是使用propensity score来对样本进行加权从而生成同分布的synthetic sample.倾向性评分加权法是一种基于个体化的标准化法。 3.倾向评分的分层(Stratification on the...
These results indicate that although trimming can improve inferences in some settings, in order to consistently improve the performance of propensity score weighting, analysts should focus on the procedures leading to the generation of weights (i.e., proper specification of the propensity score model)...
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。
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,意味着他们的X应该是很接近,如果我们能找到两个“一样”的人,他们的生活环境,年龄...

总的来说,propensity dropout的方法是很有创意的结合了神经网络的dropout和propensity score weighting,同时延续了当时multitask learning的counterfactual估计的主流思路。 代码实现 文中训练的伪代码如下图所示, training process 具体的pytorch实现可以参见, https://github.com/Shantanu48114860/Deep-Counterfactual-Networks...
Propensity score weighting is an important tool for causal inference and comparative effectiveness research. Besides the inverse probability of treatment weights (IPW), recent development has introduced a general class of balancing weights, corresponding to alternative target populations and estimands. In ...
