st: Finite population correction when testing equality of two proportions
Hi all Statalisters
I am wondering about testing two proportions in the following setting:
Infinite overall population size (for all practical purposes)
Sample 1 taken from overall population
Sample 2 subsampled from sample 1
Now I want to test if the estimated proportion having a=1 is significantly
different in sample 2 compared to sample 1.
True proportion in overall population is unknown.
Since these are not two independent samples from the same overall
population, I think I need to adjust the test by making a finite population
correction somehow for sampling sample 2 from sample 1. Only I can't find
any details on this nor a test that appears suitable in Stata.
Can anyone help?
What is the correct test?
Is there Stata-code available?
