Inference in High-dimensional Multivariate Response Regression with Hidden Variables

Xin Bing, Wei Cheng, Huijie Feng +1

This paper studies the inference of the regression coefficient matrix under multivariate response linear regressions in the presence of hidden variables. A novel procedure for cons…

Detecting approximate replicate components of a high-dimensional random vector with latent structure

Xin Bing, Florentina Bunea, Marten Wegkamp

High-dimensional feature vectors are likely to contain sets of measurements that are approximate replicates of one another. In complex applications, or automated data collection, t…

Prediction in latent factor regression: Adaptive PCR and beyond

Xin Bing, Florentina Bunea, Seth Strimas-Mackey +1

This work is devoted to the finite sample prediction risk analysis of a class of linear predictors of a response from a high-dimensional random vector $X\in \math…

Adaptive Estimation in Multivariate Response Regression with Hidden Variables

Xin Bing, Yang Ning, Yaosheng Xu

This paper studies the estimation of the coefficient matrix $\Ttheta$ in multivariate regression with hidden variables, $Y = (\Ttheta)^TX + (B^*)^TZ + E$, where is a -dimens…

Inference in latent factor regression with clusterable features

Xin Bing, Florentina Bunea, Marten Wegkamp

Regression models, in which the observed features and the response depend, jointly, on a lower dimensional, unobserved, latent vector , with $K<…
