I've followed previous steps provided on merging HIV data to couples data, and managed to merge the women's data fine. But when I go back to do the steps again to merge the men's data it says ~variable _merge already defined~ and does not merge the data.
These are the steps I was following:
** * Step 1: open AR file
use "HIV.DTA", clear
* Step 2: rename identifying variables
rename hivclust v001
rename hivnumb v002
rename hivline v003
* Step 3: sort by identifying variables
sort v001 v002 v003
* Step 4: save results
save "hiv_mergeprep.DTA", replace
* Step 5: open IR file
use "CDCR61FL.DTA", clear
* Step 6: sort by identifying variables
sort v001 v002 v003
* Step 7: merge!
merge 1:1 v001 v002 v003 using "hiv_mergeprep.DTA"
* Step 8: Keep only women
drop if _merge==2
Then rename the added hiv variables to something unique for women, e.g.
rename hiv03 w_hiv03
rename hiv01 w_hiv01
rename hiv02 w_hiv02
and repeat steps 1-8 above using mv003 instead of v003 throughout to merge the men's hiv test result and then finally rename the hiv variables to be for men, e.g.
rename hiv* m_hiv*
Is there a different way to get the male data to merge?
Thanks
