Distributed Inference for Linear Support Vector Machine
Xiaozhou Wang, Zhuoyi Yang, Xi Chen +1
The growing size of modern data brings many new challenges to existing statistical inference methodologies and theories, and calls for the development of distributed inferential ap…
First-order Newton-type Estimator for Distributed Estimation and Inference
Xi Chen, Weidong Liu, Yichen Zhang
This paper studies distributed estimation and inference for a general statistical problem with a convex loss that could be non-differentiable. For the purpose of efficient computat…
Spectral Analysis of High-dimensional Time Series
Mark Fiecas, Chenlei Leng, Weidong Liu +1
A useful approach for analysing multiple time series is via characterising their spectral density matrix as the frequency domain analog of the covariance matrix. When the dimension…
Quantile Regression Under Memory Constraint
Xi Chen, Weidong Liu, Yichen Zhang
This paper studies the inference problem in quantile regression (QR) for a large sample size but under a limited memory constraint, where the memory can only store a small batc…
