Covariate Selection for Estimating the Causal Effect of Control Plans by Using Causal Diagrams
利用因果图选择协变量以估计控制方案的因果效应
Summary Consider a case where cause–effect relationships between variables can be described by a causal path diagram and the corresponding linear structural equation model. The paper proposes a graphical selection criterion for covariates to estimate the causal effect of a control plan. For designing the control plan, it is essential to determine both covariates that are used for control and covariates that are used for identification. The selection of covariates used for…
