- Description
- This paper explores the relationship between sleep, disease, and survival, utilising shared random effects joint modelling to account for informative dropout, in a cohort of very old women. Joint modelling simultaneously models the longitudinal sleep trajectory and its effect on survival. A series of nested joint models are implemented to separate out the effects on survival of sleep and disease, the latter of which is known to have a causal role in mortality, and other factors of interest, such as self-rated health, physical functioning, mental health, vitality, baseline age, BMI, area of residence, marital status, and education. Dynamic survival predictions are also created and compared for a small sample of subjects.
