Send me the COMPLETE SUDAAN commands and I'll tell you if it is exactly
replicable in Stata or not.

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
