Cool ado-files

An archive of user contributed Stata commands is maintained by Christopher Baum (baum@bc.edu) at the Boston College Statistical Software Components Archive. Most of these commands appeared on Statalist in response to questions or as independent contributions. They are written by Stata users (including StataCorp staff) and have either not appeared in the Stata Journal or STB or are updates of commands that have appeared in the Stata Journal or STB.

Contributed Commands — Statalist ado-file Archives

When searching for Stata programs using the IDEAS search engine, we recommend including the terms "+Stata +module" to help limit the search to Stata programs and commands. For example, to locate Nicholas Cox's command for graphing horizontal bar charts we could search on "+Stata +module +bar"
