I recently have been running the STATA9 for data analysis since my department bought this version, before that, I had run by STATA8 without any problems when I used the survey command. Since I started to try to run survey command by STATA9, I got an error about the _robust2, then I checked and tried to solve problem by using the reference books, help command and searching about FAQ, but I could not get the solution yet. Therefore, I decide to ask you for some help about this big error. Would you please do me a favor, or give me some suggestion about the solution to solve this problem.
Here, this is the example about the error after I tried to run the data by using svy command.
. svyset psu_no [pweight=weight], strata(cwt) vce(linearized)
pweight: weight
VCE: linearized
Strata 1: cwt
SU 1: psu_no
FPC 1: <zero>
. svy: logit opdutil_cat3 lnhhinceq $decompose1 $decompose2
(running logit on estimation sample)
<istmt>: 3499 _robust2() not found
Mata run-time error
Thank you very much for your kindness.
Sincerely yours,
Tewarit Somkotra,DDS.
