• déjà
  • Definitions of Epidemiology
  • States vs. Events

    • 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
• New
  • (more on) Mathematical link between Incidence Density and Cumulative Incidence
     
  • Relationship between Prevalence, Incidence, and Duration in a State
     
  • Length-biased sampling
     
  • Population Pyramids Pyramids for Canada, the provinces and territories from 1901 to 2001
