See the [SVY] manual, p. 76: " svy commands use t statistics with n - L
degrees of freedom to test the significance of coefficients, where n is the
total number of sampled PSUs (clusters) and L is the number of strata in the
first stage."

The page number for the Stata 10 manual may of course differ. Watch out for
the introduction of the "svy estimation" entry.

Subject: st: P value in logistic regression models

Hi,

I am a student analyzing data from a Canadian survey for my honours project.
I am using Stata version 10. I am successfully running a number of logistic
regression models. But I have a question:  What *test* is the p value for in
my logistic regression analyses (i.e. in the output table: p>|t|)? Adjusted
Wald test with t distribution?

Here is an example of my syntax:

svy, subpop(femalesubpop_postsepviol): logistic postsepviol aborig_recode
age5 children_ex

Any help would be much appreciated.

Thank you!
Jeanette
