This page describes Stata programs developed by the UCLA IDRE Statistical Consulting Group for data analysis. You can download any of these programs from within Stata using the search command. For example, to download the cmeans command you can type search cmeans (see How can I use the search command to search for programs and get additional help? for more information about using search).
Note: In case the search command does not work, all packages are now downloadable as a ZIP file. Simply click the name of the tool and extract the contents to install the package manually.
