Subject: st: question about survey commands
Hi All,
I am working with Stata version 8.2 in Windows Vista. I am working with a
survey dataset (the Demographic and Health Surveys for India).
After generating some variables, I do a t-test to test for the equality of
means (of the relevant variables) and store some results of the test as
follows:
ttest nsibg==nsibb, unpaired unequal
local nsibeff = r(mu_1) - r(mu_2)
local g3 = r(t)
ttest nwfsb==nwfsg, unpaired unequal
local nboeff = r(mu_1) - r(mu_2)
local g4 = r(t)
(later I use these local variables).
Since the data does not come from a simple random sample, the standard
errors and test statistics are not correct. How do I go about doing the
above computations taking account of the fact that I am working with a
complex survey dataset?
I can use the *svyset* command to tell Stata the details of the survey
design (pweights, psu and strata). But I do not know how proceed after that.
Any help will be greatly appreciated.
Deepankar
