Re: st: error when using svy probit with xi

Hi All,
When I posted the above question, I did not see the discussion in this strand:
http://mail.google.com/mail/?hl=en&shva=1#inbox/12cf136dd09a1f84
Now I think the solution for this error is at least I can switch not
using xi. Just create the dummy variables.
Best wishes,
Amanda
