This post will briefly share the derivation, estimation, assumption and application of the Cox proportional hazards (PH) model. In addition, it will also mention using ANOVA to test two nested models.

This post is to share the two common non-parametric tests of comparing the survival functions: Log-Rank Test & Generalized Wilcoxon Test, as well as their corresponding calculations in the detailed process.

Concepts of survival function estimations and corresponding calculations both manually and in R.
