The cause-specific hazard functions are assumed to follow Cox proportional hazard models\, and the associations between fa ilure times given the same or different cause events and the associations between occurrences of competing risk events within the same cluster are i nvestigated through copula models. A cross-odds ratio measure is explored under our proposed models. Two-stage estimation procedure is proposed in w hich the marginal models are estimated in the first stage\, and the depend ence parameters are estimated via an Expectation-Maximization algorithm in the second stage. The proposed estimators are shown to yield consistent a nd asymptotically normal under mild regularity conditions. Simulation stud ies are conducted to assess finite sample performance of the proposed meth od. The proposed technique is demonstrated through an application to a mul ticenter Bone Marrow transplantation dataset.\n DTSTART:20180907T193000Z DTEND:20180907T203000Z LOCATION:Room 1104\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Chien-Lin (Mark) Su URL:/mathstat/channels/event/chien-lin-mark-su-289261 END:VEVENT END:VCALENDAR
