Survival Analysis

Another primary area of our research is in survival analysis and the analysis of recurrent event data. In particular, our interests focus on alternating event or recurrent exacerbation processes. These processes describe situations in which subjects alternate between exacerbations and remissions.

A key distinction between this scenario and that of standard recurrent events is the nontrivial duration of events; this makes the structure of the data differ dramatically as patients are not at risk for being re-hospitalized while they are still in-hospital. Furthermore, this makes both time-to-event and time-between-events methodologies developed for recurrent event analysis inappropriate.
