The 2-sample problem for failure rates depending on a continuous mark: an application to vaccine efficacy

PB Gilbert, IW McKeague, Y Sun - Biostatistics, 2008 - academic.oup.com
The efficacy of an HIV vaccine to prevent infection is likely to depend on the genetic variation
of the exposing virus. This paper addresses the problem of using data on the HIV sequences …

Comparison of failure probabilities in the presence of competing risks

R Bajorunaite, JP Klein - Journal of Statistical Computation and …, 2008 - Taylor & Francis
Typically, differences in the effect of treatment on competing risks are compared by a
weighted log-rank test. This test compares the cause specific hazard rates between the …

Tests for comparing mark-specific hazards and cumulative incidence functions

PB Gilbert, IW McKeague, Y Sun - Lifetime Data Analysis, 2004 - Springer
It is of interest in some applications to determine whether there is a relationship between a
hazard rate function (or a cumulative incidence function) and a mark variable which is only …

Mark-specific proportional hazards model with multivariate continuous marks and its application to HIV vaccine efficacy trials

Y Sun, M Li, PB Gilbert - Biostatistics, 2013 - academic.oup.com
For time-to-event data with finitely many competing risks, the proportional hazards model
has been a popular tool for relating the cause-specific outcomes to covariates (. The …

Omnibus tests for comparison of competing risks with adjustment for covariate effects

IW McKeague, PB Gilbert, PJ Kanki - Biometrics, 2001 - Wiley Online Library
This article develops omnibus tests for comparing cause‐specific hazard rates and
cumulative incidence functions at specified covariate levels. Confidence bands for the …

Analysis of generalized semiparametric regression models for cumulative incidence functions with missing covariates

U Lee, Y Sun, TH Scheike, PB Gilbert - Computational statistics & data …, 2018 - Elsevier
The cumulative incidence function quantifies the probability of failure over time due to a
specific cause for competing risks data. The generalized semiparametric regression models …

Testing and estimation of time-varying cause-specific hazard ratios with covariate adjustment

Y Sun, S Hyun, P Gilbert - Biometrics, 2008 - academic.oup.com
In the evaluation of efficacy of a vaccine to protect against disease caused by a genetically

Empirical Likelihood Based Test for Equality of Cumulative Incidence Functions

AM Variyath, PG Sankaran - Journal of the Indian Society for Probability …, 2020 - Springer
An empirical likelihood based test for comparing the incidence functions for multiple
competing risks is proposed, without making any assumptions on the distribution of the …

The semiparametric mark-specific proportional hazards model for multivariate marks via a single-index

Y Shao - 2020 - search.proquest.com
Competing risk analysis is commonly applied to time-to-event data with finitely many causes
of failure. It alters the probability of the occurrence of an event of interest broken down by a …

Goodness‐of‐fit tests for parametric models based on biased samples

Y Sun, S Cui, RC Tiwari - Canadian Journal of Statistics, 2002 - Wiley Online Library
The authors study the problem of checking the adequacy of a parametric model for a
distribution using several possibly censored weight biased samples. They discuss …
