Design-Based Ratio Estimators and Central Limit Theorems for Clustered, Blocked RCTs
聚类分区随机试验的设计型比率估计与中心极限定理
This article develops design-based ratio estimators for clustered, blocked randomized controlled trials (RCTs), with an application to a federally funded, school-based RCT testing the effects of behavioral health interventions. We consider finite population weighted least-square estimators for average treatment effects (ATEs), allowing for general weighting schemes and covariates. We consider models with block-by-treatment status interactions as well as restricted models…
