Counting Process Based Dimension Reduction Methods for Censored Outcomes
Qiang Sun, Ruoqing Zhu, Tao Wang +1
We propose a class of dimension reduction methods for right censored survival data using a counting process representation of the failure process. Semiparametric estimating equatio…
Dimensionality determination: a thresholding double ridge ratio criterion
Xuehu Zhu, Tao Wang, Lixing Zhu
Popularly used eigendecomposition-based criteria such as BIC type, ratio estimation and principal component-based criterion often underdetermine model dimensionality for regression…
Variable selection and estimation for semi-parametric multiple-index models
Tao Wang, Peirong Xu, Lixing Zhu
In this paper, we propose a novel method to select significant variables and estimate the corresponding coefficients in multiple-index models with a group structure. All existing a…
Transformed sufficient dimension reduction
Tao Wang, Xu Guo, Peirong Xu +1
A novel general framework is proposed in this paper for dimension reduction in regression to fill the gap between linear and fully nonlinear dimension reduction. The main idea is t…
