报告摘要:
In longitudinal observational studies, longitudinalvariables are often correlated with observation times. Also, there may exist adependent terminal event that stops the follow-up. In this article, we proposea joint modeling approach for analyzing longitudinal data with informativeobservation times and a terminal event. This approach introduces a sharedfrailty to specify the dependence structure among the longitudinal process, theobservation and terminal event times. Some estimation procedures are developedfor the model parameters and the degree of dependence. The asymptoticproperties of the proposed estimators are established. The finite sampleperformance of the proposed estimators is examined through simulation studies.An application to a medical cost study for chronic heart failure patients fromthe University of Virginia Health System is provided.
