High-Dimensional Variable Selection with Right Censored Length-biased Data

  title={High-Dimensional Variable Selection with Right Censored Length-biased Data},
  author={Di He and Yong Zhou and Hui Zou},
  journal={Statistica Sinica},
Length-biased data are inevitably encountered in various fields ranging from epidemiological cohort studies to studies of labor economics, attracting much attention in the survival literature. A crucial goal of survival analysis is to identify a subset of risk factors and their risk contributions among massive clinical covariates. However, there has been no work on variable selection for length-biased data due to the complex nature of such data and the lack of a convenient loss function. In…

Quantile regression for right-censored and length-biased data

Length-biased data arise in many important fields, including epidemiological cohort studies, cancer screening trials and labor economics. Analysis of such data has attracted much attention in the

Statistical Methods for Analyzing Right‐Censored Length‐Biased Data under Cox Model

This article proposes two estimating equation approaches for estimating the covariate coefficients under the Cox model and uses the modern stochastic process and martingale theory to develop the asymptotic properties of the estimators.

Nonparametric Estimation from Cross-Sectional Survival Data

Abstract In many follow-up studies survival data are often observed according to a cross-sectional sampling scheme. Data of this type are subject to left truncation in addition to the usual right

Length-Biased Sampling With Right Censoring

When survival data arise from prevalent cases ascertained through a cross-sectional study, it is well known that the survivor function corresponding to these data is length biased and different from

Analyzing Length-Biased Data With Semiparametric Transformation and Accelerated Failure Time Models

Two classes of flexible semiparametric models are considered: the transformation models and the accelerated failure time models, to assess covariate effects on the population failure times by modeling the length-biased times.

Variable selection in semiparametric transformation models for right-censored data

We study variable selection in general transformation models for right-censored data. The models studied can incorporate external time-varying covariates, and they include the proportional hazards

Semiparametric transformation models with length-biased and right-censored data under the case-cohort design

Case-cohort designs provide a cost effective way in large cohort studies. Semiparametric transformation models, which include the proportional hazards model and the proportional odds model as special

Buckley–James‐Type Estimator with Right‐Censored and Length‐Biased Data

This article presents a natural generalization of the Buckley-James-type estimator for traditional survival data to right-censored length-biased data under the accelerated failure time (AFT) model, and establishes the asymptotic properties of the estimators.

Asymptotic behavior of the unconditional NPMLE of the length-biased survivor function from right censored prevalent cohort data

Right censored survival data collected on a cohort of prevalent cases with constant incidence are length-biased, and may be used to estimate the length-biased (i.e., prevalent-case) survival

Penalized Generalized Estimating Equations for High‐Dimensional Longitudinal Data Analysis

A penalized generalized estimating equations procedure for analyzing longitudinal data with high‐dimensional covariates, which often arise in microarray experiments and large‐scale health studies, and one important feature of the new procedure is that the consistency of model selection holds even if the working correlation structure is misspecified.
