Package: stagsynth Type: Package Title: Staggered Synthetic Control Estimation and Inference Version: 0.1.0 Authors@R: c( person("Zhanchao", "Fu", role = c("aut", "cre"), email = "fuzhanchao2001@gmail.com"), person("Jianfei", "Cao", role = "aut", email = "jianfeicao7@gmail.com") ) Description: Implements the Staggered Synthetic Control (SSC) method for estimating treatment effects in panel data with staggered adoption, as proposed by Cao, Lu, and Wu (2020) . Constructs synthetic control weights via constrained quadratic programming, estimates heterogeneous treatment effects and event-time average treatment effects on the treated (ATT), and provides placebo-in-time confidence intervals and p-values.
