Some Two-Step Procedures for Variable Selection in High-Dimensional Linear Regression

Jian Zhang, Xinge Jessie Jeng, Han Liu

We study the problem of high-dimensional variable selection via some two-step procedures. First we show that given some good initial estimator which is $ℓ_{\infty}$ -consistent b…
