I have data from two rounds of survey conducted in the same areas (PSUs). But the individual are selected independently in both the rounds from these areas using the same statistical approaches. What would be the appropriate analysis that would be carried out to test the difference in some of the indicators between the two periods. For, example I want to test the difference in HIV prevalence between the two rounds. Is it appropriate to use the survey command by considering the PSUs are the same in both the rounds and setting the survey design according to our study. After that fitting svy: logistic to examine the difference in two rounds, is this correct way of testing the difference between the two rounds. Kindly suggest.
