摘要:Quantile regression has become a widely used tool for analyzing survival data. However, quantile regression for survival data with continuous marks is still scarce. In this article, we propose a novel mark-specific quantile regression model to address this problem. Our method borrows strength from data in a neighborhood of a mark to estimate the regression coefficients, which is very different from the existing methods for competing risks data with discrete causes. The asymptotic properties of the resulting estimators are established across mark and quantile continuums. In addition, a mark-specific quantile-type vaccine efficacy is proposed and its statistical inference procedures are developed. Simulation studies are conducted to evaluate the finite sample performances of the proposed estimation and hypothesis testing procedures. An application to the first HIV vaccine efficacy trial is provided.
