Dear all,
I have a survey data set consisting of 29 countries and roughly 50 000 respondents. I want first to draw a random sample of 10 countries and then to draw a sample of 100 respondents from each of the countries. I know how to draw a simple random sample of 1 000 respondents, but do not see any simple way to draw the two-stage sample described. Any help is greatly appreciated.
Best,
Zan
