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

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

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.

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.

A quantile regression model for failure-time data with time-dependent covariates.

This article provides a novel quantile regression model accommodating time-dependent covariates, for analyzing survival data subject to right censoring, and presents a doubly-robust estimator in the sense of Robins and Rotnitzky.

Variable selection in the accelerated failure time model via the bridge method

This article models the relationship between gene expressions and survival using the accelerated failure time (AFT) models and uses the bridge penalization for regularized estimation and gene selection, and shows that the proposed bridge estimator is selection consistent under appropriate conditions.
