  • Measures of Disease Occurrence II
    Person-time incidence rates; rate is not a proportion; average vs instantaneous incidence rates; person-time based on individual-level vs group-level data; unit of person-time in denominator does not matter; uses of rates; stratified person-time exposure in cohort studies; relationship between incidence rate and cumulative incidence via the exponential formula; use of rates in view of competing events; and the Aalen-Johansen estimator of cumulative incidence.
