ABSTRACT
Speaker: Yijian Huang, Associate Professor, Department of Biostatistics, Rollins School of Public Health, Emory University
Place: ISyE, Executive Classroom 228, Main
Time: Thursday November 15, 11:00 am
Title: Accelerated recurrence time models
For the analysis with recurrent events, we propose a generalization of the
accelerated failure time model to allow for evolving covariate effects. These so-called accelerated recurrence time models postulate that time to expected recurrence frequency, upon transformation, is a linear function of covariates with frequency-dependent coefficients. This modeling strategy shares the same spirit as quantile regression. An estimation and inference procedure is developed by generalizing the celebrated Powell's (1984, 1986) estimator for censored quantile regression. Consistency and asymptotic
normality of the proposed estimator are established. An algorithm is devised to attain good computational efficiency. Simulations demonstrate that this
proposal performs well under practical settings. This methodology is illustrated in an application to the well-known bladder cancer study.
This talk is based on joint work with Limin Peng.
