Here is a response from one of our STATA experts Tom Pullum, that should answer your question.
I will insert some lines that show the correct way to do the merge. I assume you are using Stata. I am using the "old" version of the merge syntax, which I prefer. Merges are always done with cluster number, household number, and line number.
* use the AR file
ren hivclust hv001
ren hivnumb hv002
ren hivline hv003
sort hv001 hv002 hv003
save ARtemp.dta, replace
* use the PR file
sort hv001 hv002 hv003
merge hv001 hv002 hv003 using ARtemp.dta
tab _merge
keep if _merge==3
drop _merge
* the correct weight variable will now be hiv05
The general rule about which weight to use is that hiv05 takes precedence over hv005 or v005 or mv005. If your file includes hiv05, that would be the correct weight.
The wealth index, hv270, is already coded with numbers 1 through 5. If you enter "tab hv270" you will see the labels, not the codes. If you enter "tab hv270, nolabel", you will see the codes. For more on the syntax of labels, enter "help label".
I hope this helps.
