TSCI: two stage curvature identification for causal inference with invalid instruments
TSCI:利用无效工具变量进行因果推断的两阶段曲率识别
TSCI implements treatment effect estimation from observational data under invalid instruments in the R statistical computing environment. Existing instrumental variable approaches rely on arguably strong and untestable identification assumptions, which limits their practical application. TSCI does not require the classical instrumental variable identification conditions and is effective even if all instruments are invalid. TSCI implements a two-stage algorithm. In the first…
