Veteran Lung Cancer Survival Analysis
This project analyses survival outcomes 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 using Kaplan-Meier curves, Cox proportional hazards models, diagnostic checks, spline terms, and an Aalen additive model.
The project is organised into three parts:
Overview
A concise summary of the analysis, key survival estimates, and main model findings. This is the quickest way to see the headline results.
Full Report
A full step-by-step analysis covering exploratory survival analysis, model building, functional form checks, spline terms, diagnostics, and final model interpretation.
Guide
A guided version of the analysis with collapsible sections explaining each step, the modelling choices, and the diagnostics.
