Flexible parametric survival models using Stata: Beyond the Cox Model

I have written a book with Patrick Royston titled Flexible parametric survival models using Stata: Beyond the Cox model.

You can download the datasets and code used in the book.

A review of the book can be found here.

We are writing a second edition of the book with Mark Rutherford included as an additional author.
