Conditional variable screening via ordinary least squares projection
Ning Zhang, Wenxin Jiang, Yuting Lan
In this article, we propose a novel variable screening method for linear models named as conditional screening via ordinary least squares projection (COLP). COLP can take advantage…

On the sure screening properties of iteratively sure independence screening algorithms
Ning Zhang, Wenxin Jiang, Yuting Lan
Fan and Lv (2008) proposed the path-breaking theory of sure independence screening (SIS) and an iterative algorithm (ISIS) to effectively reduce the predictor dimension for further…
