DOI: 10.1002/sim.9589
Abstract: We propose a novel two‐stage procedure for change point detection and parameter estimation in a multi‐threshold proportional hazards model. In the first stage, we estimate the number of thresholds by formulating the threshold detection problem… read more here.

DOI: 10.1080/00949655.2016.1217535
Abstract: ABSTRACT Double-censored data consist of uncensored, left- and right-censored observations and occur in survival time analysis. In this paper, parametric Bayes estimation is investigated for a proportional hazards model with durations subject to double-censoring. We… read more here.

DOI: 10.1111/biom.13413
Abstract: We study the efficiency of covariate-specific estimates of pure risk (one minus the survival function) when some covariates are only available for case-control samples nested in a cohort. We focus on the semiparametric additive hazards… read more here.
