The Cox Model and Its Applications

The Cox Model and Its Applications

The Cox Model and Its Applications published in Springer Briefs in Statistics 2016. Written by Mikhail Nikulin and Hong-Dar Isaac Wu.

I enjoyed reading this book although it has no code examples. I think I can figure out the code from the precise equations.

Cox proportional hazards model is a type of survival analysis.  The proportional hazards model was put forward by Sir David Cox in 1972.

Chapter 2 covers the basic concepts for models. Including  classical parametric models and how to handle censored data.

Chapter 3 covers the cox proportional hazards model including tampered failure time model.

Chapter 5 is about Cross-effect Models of Survival Functions.

5.2 Parametric Weibull Regression with Hetroscedastic Shape parameter.

There are lots more models. I recommend reading the book with a card you have written on explaining in a way you understand the  definitions and symbols used in the book.

 

RStudio & GitHub

Last night I learned what step I was missing to use RStudio and GitHub together. When I needed to push code to GitHub I couldn’t get it to work. This worked:

First make a repository on GitHub.

Then copy the SSH code for cloning repositories.

Open RStudio,make a new project for the repository,  go to tools tab, choose version control, pick git.

Next set up the project version control

Paste the SSH clone code in RStudio box for GitHub

Then the rest happens and RStudio is linked to GitHub and you can commit, push and pull.

I am glad I finally figured this out. Going to user groups in beneficial.
