GEEPERs: Principal Stratification using Principal Scores and Stacked Estimating Equations
GEEPERs:利用主分层评分与堆叠估计方程进行主分层分析
Principal stratification is a framework for making sense of causal effects conditioned on variables that may themselves have been affected by the treatment. For instance, in an evaluation of an educational intervention, some subjects in the treatment group may not fully utilize the intervention, and researchers may be interested in how this subgroup is affected. Most principal stratification estimators rely on strong structural or modeling assumptions and often require…
