CensoringCensored Data, Censored Observation

Censoring occurs in time-to-event data when an individual's event time is not observed exactly but is known only to lie beyond, before, or within a recorded time boundary.

Cox Proportional HazardsCox Model, Cox Regression

The Cox proportional hazards model is a semiparametric survival model that relates covariates to the instantaneous event rate while leaving the baseline hazard unspecified.

Cumulative HazardIntegrated Hazard, Accumulated Hazard

The total accumulated risk of an event by a given point in time, found by integrating the instantaneous hazard rate up to that point.

Cure ModelStatistical Cure Model, Cure-Fraction Model, Survival Cure Model

A cure model is a survival model that represents a subgroup whose disease-related excess event risk eventually disappears while accounting for the remaining risk specified by the model.
