The cumulative Kolmogorov filter for model-free screening in ultrahigh dimensional data

Published 6 Jan 2017 in stat.ME | (1701.01560v2)

Abstract: We propose a cumulative Kolmogorov filter to improve the fused Kolmogorov filter proposed by Zou (2015) via cumulative slicing. We establish an improved asymptotic result under relaxed assumptions and numerically demonstrate its enhanced finite sample performance.
