There is additional software on GitHub.

These methods are described in the book Relative Distribution Methods in the Social Sciences, by Mark S. Handcock and Martina Morris, Springer-Verlag, Inc., New York, 1999 ISBN 0387987789 .

The software can be used freely for non-commercial purposes. You may modify and distribute the code for NON-commercial purposes, as long as this statement and the above contact information is included.

While this software has now been developed and used for several years by the authors and others, a new user may well experience some problems or bugs. Please report these by email (to either handcock@stat.ucla.edu or morrism@u.washington.edu), and we will work with you to resolve the problem.

The software:

---

• R: All programs and software from the book. S-PLUS was used to construct the figures in the book. Software development is now primarily focused on R.
• S/S-PLUS: All programs and software from the book. S-PLUS was used to construct the figures in the book, and the software used is here.
• SAS macros: Macros and examples to calculate the relative data and plot the relative density. This code is much less sophisticated than the S-PLUS version, but will be updated to have as much functionality of the S-PLUS version as the structure of SAS will allow.

Description of data sources, and further information about the data sets, can be found in the book and also on the GitHub site - https://github.com/handcock/reldist.
