Figure 2. Example of dataset without over-mortality event. “Sirtuin control” dataset characteristics. Left, survival curves estimates from nonparametric and parametric estimators. Middle, corresponding hazard (mortality) estimates. Right, event plot (events distribution) of original data and 1000 samples of survival curve derivatives. Abbreviations: KM: Kaplan-Meier estimator; NA: Nelson-Aalen estimator.
