因果推断稀疏方法的信息准则

研究问题
在倾向评分分析及稀疏因果估计中,如何选择正则化参数,使变量选择的信息准则反映加权估计与双重稳健结构?
方法与思路
作者扩展Stein无偏风险估计与LASSO渐近理论,分别构造加权稀疏估计的Cp型、AIC型及双重稳健准则。
材料陈述的贡献
摘要称给出高斯模型下无需渐近论证的加权准则及一般模型下的渐近准则,并扩展到分组LASSO等正则化方法。
阅读关注点
应核对信息准则对应的风险目标、倾向评分估计的影响、准则自身双重稳健性的条件,以及不同正则化扩展。
阅读边界
这是预印本,同行评审未核验;摘要虽称多数实验优于比较准则,但未提供数值、比较设计或一般性能保证。

原文摘要

For propensity score analysis and sparse estimation, we develop an information criterion for determining the regularization parameters needed in variable selection. First, for Gaussian distribution-based causal inference models, we extend Stein's unbiased risk estimation theory, which leads to a generalized Cp criterion that has almost no weakness in conventional sparse estimation, and derive an inverse-probability-weighted sparse estimation version of the criterion without resorting to asymptotics. Next, for general causal inference models that are not necessarily Gaussian distribution-based, we extend the asymptotic theory on LASSO for propensity score analysis, with the intention of implementing doubly robust sparse estimation. From the asymptotic theory, an AIC-type information criterion for inverse-probability-weighted sparse estimation is given, and then a criterion with double robustness in itself is derived for doubly robust sparse estimation. Numerical experiments compare the proposed criterion with the existing criterion derived from a formal argument and verify that the proposed criterion is superior in almost all cases, that the difference is not negligible in many cases, and that the results of variable selection differ significantly. Real data analysis confirms that the difference between variable selection and estimation by these criteria is actually large. Finally, generalizations to general sparse estimation using group LASSO, elastic net, and non-convex regularization are made in order to indicate that the proposed criterion is highly extensible.
