This flexible methodology is used across many scientific disciplines with varying names such as event‐history analysis, failure‐time analysis, and hazard analysis. Survival Analysis courses from top universities and industry leaders. .sidebar ul { R is one of the main tools to perform this sort of analysis thanks to the survival package. Survival analysis can handle right censoring, staggered entry, recurrent events, competing risks, and much more as long as we have available representative risk sets at each time point to allow us to model and estimate event rates. } div{ The Kaplan-Meier estimator is a statistic used to estimate a survival function.
