2604.01394 Causal Forests with Honest Splitting Have Asymptotically Normal Treatment Effects Even Under 20% Attrition: A Trimming Bounds Extension
This paper investigates the econometric foundations underlying causal forests with honest splitting have asymptotically normal treatment effects even under 20% attrition: a trimming bounds extension. Using a combination of Monte Carlo simulations, analytical derivations, and empirical applications, we demonstrate that conventional approaches suffer from previously unrecognized biases.
