Hi,
I have a problem with the command svyselmlog.
Stata help says that:
svyselmlog requires that the survey design variables be identified using
svyset, see help svyset
I found in the site
http://www.ats.ucla.edu/stat/Stata/faq/svy_introsurvey.htm an
application of svyset
So, in Stata I did:
use http://www.ats.ucla.edu/stat/stata/faq/svysmall, clear
gen xx=uniform()
gen dummy = 0 if xx>0.6
replace dummy = 1 if dummy==. (so I generated a dummy variable 0 - 1)
svyset house [pweight = wt], strata(eth)
svy: regress y x1 x2 x3 (the regression works)
But, if I run the svyselmlog command in the following way:
svyselmlog dummy x1 x2, select(dummy x1 x2 x3)
Stata says:
Data not set up for the old survey estimation commands; use svyset under
version control or use the new svy prefix.
What can I do to run svyselmlog?
Thanks in advance
Riccardo Magnani
