Changes

The hazard function describes the pattern of the 'incidence rate' over time (rather than summing an 'average' estimate over the duration of the study, as with the incidence rate itself). Although the hazard function may be described graphically, it is most commonly used in analytic studies, when hazard functions are compared in the form of a hazard ratio (a [[Measures of strength of association|measure of strength of association]]).
