Parallel subgroup analysis of high-dimensional data via M-regression

Chao Cheng, Xingdong Feng

It becomes an interesting problem to identify subgroup structures in data analysis as populations are probably heterogeneous in practice. In this paper, we consider M-estimators to…

$ℓ_{0}$ -Regularized High-dimensional Accelerated Failure Time Model

Xingdong Feng, Jian Huang, Yuling Jiao +1

We develop a constructive approach for $ℓ_{0}$ -penalized estimation in the sparse accelerated failure time (AFT) model with high-dimensional covariates. Our proposed method is bas…
