Hi, Statlisters.
I hope you can help.
I have been exploring a publically avail dataset (NHAMCS), which includes 
all weighting variables, and their documentation says I should be able to 
get accurate estimates and SE using STATA.
However, my statistical colleague uses SUDAAN. I have been able to match 
her point estimates, but not SE.
We discovered that she uses many more weighting variables in SUDAAN than 
STATA requires.

So my command looks like:

svydes:
pweight: patwt
strata:stratm1
PSU: psum

xi: svylogit outcome var1 var 2 i.var1*var2 patwt, str(stratm1) 
psu(psum)sub(sample) or

Wheras in SUDAAN, Jane uses all of the following:
stratm psum subfile prostrat su poppsum popsu popvism popprovm
( and sets levels)

Am I missing the finite pop ct variable? (fpc)
Anyone else use STATA for NHAMCS?

Can Stata handle interaction terms in svy data?

Many thanks.
Jill Huppert
