This project presents a comprehensive survival analysis of the rats dataset using non-parametric, semi-parametric, and parametric methods. It integrates Kaplan–Meier and Nelson–Aalen estimators, hypothesis testing, and Cox proportional hazards models to evaluate treatment and sex effects on tumour development. The study further assesses model assumptions, performs diagnostics, and refines models to address violations, providing a robust comparison of survival modelling approaches and their practical interpretation in biomedical research.
