Robert: You may want to consider using
lincom
or
test.
if you are running version 8. In prior versions of Stata, I
believe that the commands were svylincom and svytest. You can
find examples using the two commands are given in the Stata
help file and in the manual. Then, there is the excellent UCLA
site,
http://www.ats.ucla.edu/stat/stata/topics/Survey.htm .
However, there is not a specific command for conducting a oneway
analysis of variance.
