Lecture: Intro to Epidemiology and Measures of Occurrence
- Definitions of Epidemiology
- States vs. Events
- Population
An aggregate of people, defined by membership-defining...
- event -> "cohort" ( closed population i.e. closed for exit)
or
- state - for duration of state -> Open population (open for exit) / dynamic / turnover
- Prevalence (of a state)
- Population-time
- Incidence ( new events in members "at risk" for the event )
- Incidence density (momentary or average over a span of time)
- Hazard (momentary, but more commonly used w.r.t a closed population)
- Force of morbidity/mortality / Intensity
- Cumulative Incidence (over a span of cohort time), and associated terms
- Risk
- its complement: Survival proportion
- Mathematical link between Incidence Density and Cumulative Incidence
