Stata Programs forData Analysis This page describes Stata programs developed by the UCLA ATS Statistical Consulting Group for data analysis. You can download any of these programs from within Stata using the findit command. For example, to download the cmeans command you can type findit cmeans (see How can I used the findit command to search for programs and get additional help? for more information about using findit ).
