Quasi-Bayesian Estimation and Inference with Control Functions

no code implementations27 Feb 2024 Ruixuan Liu, Zhengfei Yu

We consider a quasi-Bayesian method that combines a frequentist estimation in the first stage and a Bayesian estimation/inference approach in the second stage.

Double Robust Bayesian Inference on Average Treatment Effects

no code implementations29 Nov 2022 Christoph Breunig, Ruixuan Liu, Zhengfei Yu

We propose a double robust Bayesian inference procedure on the average treatment effect (ATE) under unconfoundedness.

Rethinking Feature Uncertainty in Stochastic Neural Networks for Adversarial Robustness

no code implementations1 Jan 2022 Hao Yang, Min Wang, Zhengfei Yu, Yun Zhou

Extensive experiments on well-known white- and black-box attacks show that MFDV-SNN achieves a significant improvement over existing methods, which indicates that it is a simple but effective method to improve model robustness.

Inference on Individual Treatment Effects in Nonseparable Triangular Models

no code implementations12 Jul 2021 Jun Ma, Vadim Marmer, Zhengfei Yu

In nonseparable triangular models with a binary endogenous treatment and a binary instrumental variable, Vuong and Xu (2017) established identification results for individual treatment effects (ITEs) under the rank invariance assumption.

Empirical Likelihood Covariate Adjustment for Regression Discontinuity Designs

no code implementations21 Aug 2020 Jun Ma, Zhengfei Yu

In addition, the coverage accuracy of the RCEL confidence set is automatically robust against slight perturbation to the covariate balance condition, which may happen in cases such as data contamination and misspecified "unaffected" outcomes used as covariates.
