I am trying to obtain estimates related to poverty by race from IPUMS-USA based on ACS 2012-2016 5-year sample (e.g., the percentage of African American children below the poverty level).
I would like to calculate standard errors for my estimates. When I tried the following SAS code, I got an error that my repwtp2 is negative.
proc surveyfreq data=set1;
repweights REPWTP1-REPWTP80 / jkcoefs= 0.05 ;
Is the above code correct? And if so, how do I address the issue of the negative rep weights?
