The goal of the analysis is to use some methods namely: Kaplan–Meier estimator, Log-Rank Test, Cox Proportional Hazard, Machine Learning, and Cross-Validation, to assess the benefit of some selected covariates on survival. The basic analysis, that I did, can be done using PBC dataset and the functions in R package "survival", alongside some other packages.
This code is meant to be used as either a research tool or a study guide for anyone interested in learning about Survival Analysis.
