Statistical Inference for Linear Mediation Models with High-dimensional Mediators and Application to Studying Stock Reaction to COVID-19 Pandemic
Xu Guo, Runze Li, Jingyuan Liu +1
Mediation analysis draws increasing attention in many scientific areas such as genomics, epidemiology and finance. In this paper, we propose new statistical inference procedures fo…
A projection-based model checking for heterogeneous treatment effect
Niwen Zhou, Xu Guo, Lixing Zhu
In this paper, we investigate the hypothesis testing problem that checks whether part of covariates / confounders significantly affect the heterogeneous treatment effect given all…
The Role of Propensity Score Structure in Asymptotic Efficiency of Estimated Conditional Quantile Treatment Effect
Niwen Zhou, Xu Guo, Lixing Zhu
When a strict subset of covariates are given, we propose conditional quantile treatment effect to capture the heterogeneity of treatment effects via the quantile sheet that is the…
A New Procedure for Controlling False Discovery Rate in Large-Scale t-tests
Changliang Zou, Haojie Ren, Xu Guo +1
This paper is concerned with false discovery rate (FDR) control in large-scale multiple testing problems. We first propose a new data-driven testing procedure for controlling the F…
Testing heteroscedasticity for regression models based on projections
Falong Tan, Xuejun Jiang, Xu Guo +1
In this paper we propose a new test of heteroscedasticity for parametric regression models and partial linear regression models in high dimensional settings. When the dimension of…
