Statistical Inference For Noisy Matrix Completion Incorporating Auxiliary Information

no code implementations22 Mar 2024 Shujie Ma, Po-Yao Niu, Yichong Zhang, Yinchu Zhu

This paper investigates statistical inference for noisy matrix completion in a semi-supervised model when auxiliary covariates are available.

Semidiscrete optimal transport with unknown costs

no code implementations1 Oct 2023 Yinchu Zhu, Ilya O. Ryzhov

Semidiscrete optimal transport is a challenging generalization of the classical transportation problem in linear programming.

New possibilities in identification of binary choice models with fixed effects

no code implementations21 Jun 2022 Yinchu Zhu

We provide a condition called sign saturation and show that this condition is sufficient for the identification of the model.

Optimal data-driven hiring with equity for underrepresented groups

no code implementations19 Jun 2022 Yinchu Zhu, Ilya O. Ryzhov

We present a hiring policy that depends on the protected attribute functionally, but not statistically, and we prove that, among all possible fair policies, ours is optimal with respect to the firm's objective.

Phase transition of the monotonicity assumption in learning local average treatment effects

no code implementations24 Mar 2021 Yinchu Zhu

This boundary of phase transition is explicitly characterized in the case of binary outcomes.

Comments on Leo Breiman's paper 'Statistical Modeling: The Two Cultures' (Statistical Science, 2001, 16(3), 199-231)

no code implementations21 Mar 2021 Jelena Bradic, Yinchu Zhu

Breiman challenged statisticians to think more broadly, to step into the unknown, model-free learning world, with him paving the way forward.

Minimax Semiparametric Learning With Approximate Sparsity

no code implementations27 Dec 2019 Jelena Bradic, Victor Chernozhukov, Whitney K. Newey, Yinchu Zhu

This paper is about the feasibility and means of root-n consistently estimating linear, mean-square continuous functionals of a high dimensional, approximately sparse regression.

Distributional conformal prediction

1 code implementation17 Sep 2019 Victor Chernozhukov, Kaspar Wüthrich, Yinchu Zhu

We propose a robust method for constructing conditionally valid prediction intervals based on models for conditional distributions such as quantile and distribution regression.

Sparsity Double Robust Inference of Average Treatment Effects

no code implementations2 May 2019 Jelena Bradic, Stefan Wager, Yinchu Zhu

Many popular methods for building confidence intervals on causal effects under high-dimensional confounding require strong "ultra-sparsity" assumptions that may be difficult to validate in practice.

A $t$-test for synthetic controls

1 code implementation27 Dec 2018 Victor Chernozhukov, Kaspar Wuthrich, Yinchu Zhu

We propose a practical and robust method for making inferences on average treatment effects estimated by synthetic controls.

Testability of high-dimensional linear models with non-sparse structures

no code implementations26 Feb 2018 Jelena Bradic, Jianqing Fan, Yinchu Zhu

Uniform non-testability identifies a collection of alternatives such that the power of any test, against any alternative in the group, is asymptotically at most equal to the nominal size.

Breaking the curse of dimensionality in regression

no code implementations1 Aug 2017 Yinchu Zhu, Jelena Bradic

In this article, we are interested in conducting large-scale inference in models that might have signals of mixed strengths.

A projection pursuit framework for testing general high-dimensional hypothesis

no code implementations2 May 2017 Yinchu Zhu, Jelena Bradic

We propose a new inference method developed around the hypothesis adaptive projection pursuit framework, which solves the testing problems in the most general case.

Two-sample testing in non-sparse high-dimensional linear models

no code implementations14 Oct 2016 Yinchu Zhu, Jelena Bradic

In analyzing high-dimensional models, sparsity of the model parameter is a common but often undesirable assumption.

Linear Hypothesis Testing in Dense High-Dimensional Linear Models

no code implementations10 Oct 2016 Yinchu Zhu, Jelena Bradic

The test statistics are constructed in such a way that lack of sparsity in the original model parameter does not present a problem for the theoretical justification of our procedures.

Significance testing in non-sparse high-dimensional linear models

no code implementations7 Oct 2016 Yinchu Zhu, Jelena Bradic

We show that existing inferential methods are sensitive to the sparsity assumption, and may, in turn, result in the severe lack of control of Type-I error.
