and for both.

But in Stata 10, the same commands give this error:

Unknown function index()

r(133);

I'll email Scott Long about it. I don't know if his programs need updating or if there is a bug (with version control?) in Stata 10.

A little more tedious, but I think you could also standardize yourself:

webuse nhanes2f

svy: reg weight age

center weight age [aw=finalwgt] if e(sample), standardize

svy: reg c_weight c_age

You need to install -center- first (available from ssc). And, unless you have no missing data, you may have to do the centering each time for each regression.

The usual caveats about standardized coefficients being the work of the Devil continue to apply. There may also be additional concerns about using them with svy.
