Dear All,
I have a question about systematic sampling. I have read the Stata
manuals but I still cannot identify the PSUs and stratas in my data, and
I am not very sure about how to handle the systematic sampling. In broad
terms, I cannot match the textbook with my case...
Basically, I am using a census, in which the whole population for rural
areas and cities of less than 100.000 inhabitants were interviewed. In
cities with 100.000-500.000, I am told that 1 out of five "segments"
were systematically selected, and in cities of more than 500.000, 1 in
10 "segments" were selected. The "segments" are units of around forty
houses assigned to each each interviewer.
Finally, the weights are the inverse of the probability of being
included (so for rural areas and small cities they are just one). The
resulting sample (more than 16 million observations) is half the total
population.
I am unsure about how to deal with this within Stata, since for half of
my data I have the whole population whereas for the other I only have a
(complex) sample.
Any help will be appreciated.
Thank you all!
best,
g.
