“…However, we have to acknowledge that the improvements remain modest. Other procedures than ISIS have been recently proposed, but are not yet implemented, nor the code provided with the original article [ 72 , 73 ]. A benchmark among all these procedures would be an interesting perspective.…”

“…The results of Case (c) demonstrate that CDC-SIS procedure performs well no matter for the completely random censoring mechanism or the informative censoring mechanism. Moreover, the results of Case (d) show that the proposed procedure is robust to 𝑝, the number of covariates; 𝜎 1 = 1; 𝜎 2 = (𝑍 2 1 + 𝑍 2 2 + 𝑍 2 3 ) −1 ; FAST: the screening procedure of Gorst-Rasmussen & Scheike (2013); P-SIS: the screening procedure of Zhao & Li (2012); CRIS: the screening procedure of Song et al (2014); CCRIS: the screening procedure of Zhang et al (2018); C-SIRS: the screening procedure of Zhou & Zhu (2017); DCSIS: the screening procedure of Zhang et al (2021); COXCS: the conditional screening procedure of Hong et al (2018); CDC-SIS: the proposed CDC-based conditional screening procedure.…”

“…Gene AA805575, a Germinal-center B-cell signature gene has been known to be predictive to DCBCL patients' survival time in the literature (e.g., Gui & Li, 2005;Liu et al, 2013), we treat it as the conditional variable in our proposed procedure. In particular, we first apply the proposed CDC-SIS procedure to screen the important ones among the 7399 genes and select 𝑝, the number of covariates; 𝜎 1 = 1; 𝜎 2 = (𝑍 2 1 + 𝑍 2 2 + 𝑍 2 3 ) −1 ; FAST: the screening procedure of Gorst-Rasmussen & Scheike (2013); P-SIS: the screening procedure of Zhao & Li (2012); CRIS: the screening procedure of Song et al (2014); CCRIS: the screening procedure of Zhang et al (2018); C-SIRS: the screening procedure of Zhou & Zhu (2017); DCSIS: the screening procedure of Zhang et al (2021); COXCS: the conditional screening procedure of Hong et al (2018); CDC-SIS: the proposed CDC-based conditional screening procedure.…”

“…Many authors have considered the generalizations of the SIS procedure to the screening of important features based on right-censored failure time data. In general, the developed procedures can be classified into two types, model-based ones (Tibshirani, 2009;Fan, Feng and Wu, 2010;Zhao and Li, 2012;Gorst-Rasmussen and Scheike, 2013) and modelfree methods (Song et al, 2014;Wu and Yin, 2015;Zhang, Liu and Wu, 2017;Zhou and Zhu, 2017;Liu, Zhang and Zhao, 2018;Zhang et al, 2018;Lin, Liu and Hao, 2018;Zhang, Liu and Cui, 2020). However, limited SIS methods have been studied for IC failure time data.…”
