DOI: 10.1007/s00362-019-01128-5
Abstract: In modern statistical applications, the dimension of covariates can be much larger than the sample size, and extensive research has been done on screening methods which can effectively reduce the dimensionality. However, the existing feature… read more here.

DOI: 10.1016/j.jkss.2018.11.003
Abstract: Abstract This paper is concerned with the stable feature screening for the ultrahigh dimensional data. To deal with the ultrahigh dimensional data problem and screen the important features, a set-averaging measurement is proposed. The model… read more here.

DOI: 10.1080/00949655.2020.1783666
Abstract: This paper is concerned with feature screening for the ultrahigh dimensional additive models with longitudinal data. The proposed method utilizes the quadratic inference functions to construct the marginal screening measurement, which takes the within-subject correlation… read more here.

DOI: 10.1080/00949655.2021.1981901
Abstract: Existing model-free ultra-high-dimensional feature screening methods mainly focus on the individual covariate. However, many variables have a community structure, such as grouped covariates in which all variates have high correlation and some associations in one… read more here.

DOI: 10.1111/biom.13658
Abstract: A novel feature screening method is proposed to examine the correlation between latent responses and potential predictors in ultrahigh dimensional data analysis. First, a confirmatory factor analysis (CFA) model is used to characterize latent responses… read more here.

DOI: 10.3390/math11102398
Abstract: Ultrahigh-dimensional grouped data are frequently encountered by biostatisticians working on multi-class categorical problems. To rapidly screen out the null predictors, this paper proposes a quantile-composited feature screening procedure. The new method first transforms the continuous… read more here.
