Estimating the hazard function typically involves survival data and various statistical techniques. Some common methods include:
1. Kaplan-Meier Estimator: This non-parametric method estimates the survival function and can be used to derive the hazard function. 2. Cox Proportional Hazards Model: A semi-parametric model that estimates the hazard function while adjusting for covariates. 3. Parametric Models: These include exponential, Weibull, and Gompertz models, which assume specific distributions for the survival times.
