In Stata 8, -svyprop- doesn't save anything in e() and what is saves in r() is
not very helpful to users. The good news is that you can use a combination of
the -xi:- prefix with -svymean- to get the estimated proportions in e(b).
Here is an example using the auto dataset:
. sysuse auto
. svyset, srs
. xi: svymean i.rep78, by(foreign)
In the above, we use -svymean- to estimate the proportions for
each category of -rep78- for each subpopulation defined by the categories for
-foreign-.
In Stata 9, the -svy: proportion- command actually saves in e(); thus you do
not need -xi- and -svy: mean-. In this case the above example is:
. sysuse auto
. svyset _n
. svy: proportion rep78, by(foreign)
