We formulate the effects of potentially time-varying covariates on the multivariate event times through marginal proportional hazards models while leaving the dependence structures of the related event times unspecified. We construct the nonparametric pseudolikelihood under the working assumption that all event times are independent, and we provide a simple and stable EM-type algorithm. The resulting nonparametric maximum pseudolikelihood estimators for the regression parameters are shown to be consistent and asymptotically normal, with a limiting covariance matrix that can be consistently estimated by a sandwich estimator under arbitrary dependence structures for the related event times. We evaluate the performance of the proposed methods through extensive simulation studies and present an application to data from the Atherosclerosis Risk in Communities Study.<\/jats:p>","DOI":"10.1093\/biomet\/asac059","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T19:21:03Z","timestamp":1667416863000},"page":"815-830","source":"Crossref","is-referenced-by-count":7,"title":["Marginal proportional hazards models for multivariate interval-censored data"],"prefix":"10.1093","volume":"110","author":[{"given":"Yangjianchen","family":"Xu","sequence":"first","affiliation":[{"name":"University of North Carolina Department of Biostatistics, , 3101E McGavran-Greenberg Hall, Chapel Hill, North Carolina 27599, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donglin","family":"Zeng","sequence":"additional","affiliation":[{"name":"University of North Carolina Department of Biostatistics, , 3101E McGavran-Greenberg Hall, Chapel Hill, North Carolina 27599, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D Y","family":"Lin","sequence":"additional","affiliation":[{"name":"University of North Carolina Department of Biostatistics, , 3101E McGavran-Greenberg Hall, Chapel Hill, North Carolina 27599, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,11,2]]},"reference":[{"key":"2023081420143871000_B1","first-page":"1023","article-title":"A profile likelihood theory for the correlated gamma-frailty model with current status family data","volume":"17","author":"Chang,","year":"2007","journal-title":"Statist.
