A Markov Transition Model To Dementia With Death As A Competing Event, Liou Xu
A Markov Transition Model To Dementia With Death As A Competing Event, Liou Xu
University of Kentucky Doctoral Dissertations
The research on multi-state Markov transition model is motivated by the nature of the longitudinal data from the Nun Study (Snowdon, 1997), and similar information on the BRAiNS cohort (Salazar, 2004). Our goal is to develop a flexible methodology for handling the categorical longitudinal responses and competing risks time-to-event that characterizes the features of the data for research on dementia. To do so, we treat the survival from death as a continuous variable rather than defining death as a competing absorbing state to dementia. We assume that within each subject the survival component and the Markov process are linked by …
