Veteran Lung Cancer Survival Analysis
This project looks at how long patients survived in the Veterans Administration lung cancer trial, a classic dataset for time-to-event modelling in R. It compares standard and experimental chemotherapy in patients with advanced, inoperable lung cancer, and uses Kaplan-Meier curves and Cox proportional hazards models to work out what actually predicts survival.
The project comes in two parts:
