摘要：

Approaches to estimate treatment effects in panel data with only one treated unit have become  popular in applied works, which include synthetic control method (Abadie and Gardeazabal, 2003, Abadie et al., 2010), and regression control method (Hsiao et al., 2012). However, no pointwise standard errors or confidence intervals for the treatment effects have been provided or rigorously proven in the literature yet.  

We propose a direct nonparametric construction of pointwise robust confidence intervals using quantile random forest (QRF), i.e. quantile regression via random forest.This is called “Quantile Control Method”(QCM).

Monte Carlos simulations show good coverage probability for the confidence intervals, which are robust to heteroskedasticity, autocorrelation, and model misspecification.
