A timeline of research in frailty models with Professor Ralph D'Agostino, Sr.

Music City Center 

From a pressing unresolved data analysis issue inspired from the Framingham Heart Study to developing a tutorial as part of his journal, Statistics in Medicine, Professor D'Agostino had thought provoking ideas in survival analysis and led by real world examples which inspired his ideas for research. Coming across an idea for how to model the survival of participants in the study who had an atrial fibrillation event and went on to have a stroke event, D'Agostino got an idea of how to handle the differences seen in the observed data of differential hazards rates amongst this population with a newer way of modeling this data. His idea then convinced me to pursue this line of research and lead me on a long journey of researching frailty models and novel developments in this area. Later on, we continued this research by writing a tutorial in frailty models and subsequently after this in his later years we again wrote a review of survival modeling which encompassed frailty as well as more modern techniques for modeling. I will present these joint research to demonstrate D'Agostino's guidance and thought provoking research.
