-This is a practice of survival analysis concepts on an existing dataset, analysis using R code and interpretation. Suggestions for improvement always welcome. 
+This repository presents a complete survival analysis of HIV patients who experienced failure with zidovudine therapy, using the `aids` and `aids.id` datasets from the `JM` package. The project showcases not only advanced modeling but also careful data exploration, assumption checking, and clear interpretation using reproducible R workflows.
