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!
