Red Door Analytics

People move between states rather than out of one — well to ill to dead — and each arrow carries its own hazard. How long someone spends in a state, and where the cohort is at five years, are consequences of those hazards rather than separate estimands.

Also called multistate survival, illness-death models.

A narrower method under survival analysis.

Multi-state models: The transition graph, each arrow weighted by the transitions the cohort actually made.
The transition graph, each arrow weighted by the transitions the cohort actually made. Those intensities are the entire model — how long people spend in each state, and how many are alive and well at five years, are consequences of them rather than separate estimands.
