Terminal Behavior of Recurrent Marker Processes
Keywords: medical costs, recurrent events, survival analysis
Recurrent marker processes, such as repeated hospitalizations and medical costs, often exhibit certain terminal behavior before informative terminal events, such as death. For example, medical costs tend to increase in a short period of time before death. To study such a terminal behavior, we propose a semiparametric three level regression model to study jointly the survival time, recurrent event processes and marker processes before failure events. Statistical methods are proposed using risk set methodologies.
