What are Hazard Functions and Survival Functions?

The hazard function and survival function are key concepts in survival analysis:
Hazard Function: This represents the instantaneous rate at which the event of interest occurs, given that the individual has survived up to that point. It is often used in the Cox proportional hazards model.
Survival Function: This represents the probability that an individual survives from the starting point up to a certain time. It is commonly estimated using the Kaplan-Meier estimator.
