How about
. gen x1=x==1
. gen x2=x==2
. svyreg y x1 x2
. test x1
for starters? The -svytest- command has been supplanted by -test-, FYI.

Subject: st: stumped with lincom after svymean
Hi Listers -
Here is what I am trying to accomplish. I have a continuous variable y, and
a categorical variable x. The categorical variable x has three categories:
0, 1, and 2. I want to test whether y is different among the categories of
my variable x. My data are collected using a stratfied, cluster design and
therefore I must use the survey commands.
In previous versions of stata, I would use the code:
svymean y, by(x)
svytest [x]0=[x]1
Stata 8 says that svytest no longer exists and that I should use the lincom
command. Maybe the coffee hasn't set in, but I cannot figure out how to do
replicate the above code using the lincom command based on the information
from Stata's help screen.
So my question is two-fold:
1 - How do I test group differences using the svy command in Stata 8 based
on my above example?
2 - Is it possible to estimate a one-way anova to detect group differences
with svy commands in Stata 8 based on my above example?
Thanks in advance for your help!
Robert
