Subject |
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?

Regards,

Fredrik
