st: controlling the omission of dummy variables

["Dimitriy V. Masterov" <dvmaster@lily.src.uchicago.edu>]

Dear Statalist,

I can't seem to figure out how to alter what the Stata criteria are for
dropping one dummy variable from a collinear set of such variables in an
OLS regression. Is there a command that sets it to be the most common
category, the way one can do with xi using char _dta[omit] "prevalent" ?
