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.

Testability of Reverse Causality without Exogeneous Variation

no code implementations13 Jul 2021 Christoph Breunig, Patrick Burauel

Instead of relying on exogenous variation, we achieve testability by imposing relatively weak model restrictions.

Simple Adaptive Estimation of Quadratic Functionals in Nonparametric IV Models

no code implementations28 Jan 2021 Christoph Breunig, Xiaohong Chen

This paper considers adaptive, minimax estimation of a quadratic functional in a nonparametric instrumental variables (NPIV) model, which is an important problem in optimal estimation of a nonlinear functional of an ill-posed inverse regression with an unknown operator.

Nonclassical Measurement Error in the Outcome Variable

no code implementations26 Sep 2020 Christoph Breunig, Stephan Martin

We study a semi-/nonparametric regression model with a general form of nonclassical measurement error in the outcome variable.

Adaptive, Rate-Optimal Hypothesis Testing in Nonparametric IV Models

no code implementations17 Jun 2020 Christoph Breunig, Xiaohong Chen

We propose a new adaptive hypothesis test for inequality (e. g., monotonicity, convexity) and equality (e. g., parametric, semiparametric) restrictions on a structural function in a nonparametric instrumental variables (NPIV) model.
