• Seminar by Darby Thompson (Thursday, February 16, 2012)
  Time: 3:30pm-4:30pm and Room: WSC 248
  Speaker: Darby Thompson, Simon Fraser University
  Title: Joint Analysis of Longitudinal and Time-to-Event Outcomes with an application to Interval-Censored Data
  

  How do I handle study dropout and missing data? How much can I really trust this biomarker? How can I tell if a therapy really works when there are 6 ways to measure this condition? It's possible that a joint model can provide some insights to all these questions and more. With minimal mathematical detail, this talk will introduce the concept of jointly modeling with particular attention to data collected over time, and the time to an event. Examples include PSA and time to metastasis in prostate cancer, CD4 counts and time to progression to AIDS, or QOL measures and remaining lifetime. Modeling assumptions, strategies, characteristics and limitations will be described. In addition, interval-censored time-to-event data is very common where subject compliance is poor, the time-to-event is very long, or the confirmation of events is difficult/expensive. New work describing the utility of joint modeling in these scenarios will also be presented with an application to a designed experiment.
