These pages contain Stata commands and Stata programs with a minimum of documentation or explanation. These pages often reflect samples that we have created in solving a problem for someone during consulting. If we do not have time to make a proper FAQ or Learning Module, we place the example program here so it may be publicly available until we have time to make a proper FAQ page or Learning Module page. Until then, we hope that these example may prove useful to some of you. If you are not sure if you are properly using any of these code fragments (and you are a member of the UCLA research community) please use our consulting services so we may help you properly use these examples. Many of these examples are tricky and complicated, so if you are in doubt, please let us assist you.
