Survival Analysis
Analyze Survival Time Data
Survival data contain duration times until the occurrence of a specific event and are sometimes referred to as event-time response data. The event is usually failure, such as the failure of an engine or death of a patient. If the event does not occur before the end of a study for an observation, the observation is said to be censored.
The Survival platform fits a single Y that represents time to event (or time to failure). Use the Survival platform to examine the distribution of the failure times.
Tip: To fit explanatory models, use the Fit Parametric Survival platform or the Fit Proportional Hazards platform.
