dear all,
I have aggregated data:
year X sex X age X education level X labor force participation (7x2x9x4x2)
these data are from the whole population and I would like to make random sample from them, but they are to big to do that,
do you have any idea how I can do that?
what I did: I use STATA 9.1/SE and first of all I changed my memory to 950m
after that I transformed aggregated data to individual data by
expand f
it consumed a lot of time but it was ok
after that I tried to do random sample to have at each table 1000 respondents
bsample 1000, strata(year sex age)
I left the computer to work on it during the weekend but it is not completed yet, so I think that it is not possible to do,
do you have any idea how to do random sample if I have so big data?
thanks, tomas
