Regression Methods in Biostatistics

This page contains R scripts for doing the analysis presented in the book entitled Regression Methods in Biostatistics (Eric Vittinghoff, David V. Glidden, Stephen C. Shiboski, and Charles E. McCulloch, Springer 2005). A short summary of the book is provided elsewhere, on a short post (Feb. 2008).

Analysis were carried out using Stata and the corresponding scripts are available on the companion website. However, some of the data are not provided. I have asked for the entire data sets used throughout the book, but I don't get any response from the authors.

Individual files are available in the table below. Chapter scripts include: the R script itself and its htmlized version, the output as a log file, a pdf of the generated figures. Exercises scripts include the R scripts and their htmlized version. Exercises solutions are compiled on a separate html page, produced with asciidoc. Exercises solutions in html format are about 15-20 printed pages.
I also compiled a quick and dirty handbook for all exercises solutions: RMB Solutions Handbook. This textbook was generated by compiling all asciidoc pages into a single Docbook document, then converting it to pdf using a custom shell script.-->

As an alternative, you can download the whole chapters and solutions scripts, as well as the data sets:

Analyses have been done with R version 2.6.2 (2008-02-08) and 2.7.1 (2008-06-23) running on Mac OS X.
