Is levels an ado file or an option of some command? I cannot find it.


What version of Stata are you using? -help levels- produces info in Stata 8. It is an ado file.
In the latest Stata 8, -levels- is an official Stata ado-file. However, in Stata 7, and in earlier versions of Stata 8, -levels- was an unofficial Stata ado-file, downloadable from SSC. If Anna has Stata 7, then the way to find out more is to type

ssc desc levels

If Anna has an early version of Stata 8, then the ideal solution is to update to the latest Stata 8. (See on-line help for -update-.) If this is not possible, then the best thing to do is to download the version on SSC.

I hope this helps.
