Two Robust Tools for Inference about Causal Effects with Invalid Instruments
Hyunseung Kang, Youjin Lee, T. Tony Cai +1
Instrumental variables have been widely used to estimate the causal effect of a treatment on an outcome. Existing confidence intervals for causal effects based on instrumental vari…
Testing Endogeneity with High Dimensional Covariates
Zijian Guo, Hyunseung Kang, T. Tony Cai +1
Modern, high dimensional data has renewed investigation on instrumental variables (IV) analysis, primarily focusing on estimation of effects of endogenous variables and putting lit…
A simple and robust confidence interval for causal effects with possibly invalid instruments
Hyunseung Kang, T. Tony Cai, Dylan S. Small
Instrumental variables have been widely used to estimate the causal effect of a treatment on an outcome. Existing confidence intervals for causal effects based on instrumental vari…
An adaptation theory for nonparametric confidence intervals
T. Tony Cai, Mark G. Low
A nonparametric adaptation theory is developed for the construction of confidence intervals for linear functionals. A between class modulus of continuity captures the expected leng…
