Dear Stata-users,
I have a household roster data file which consists of about 20 variables
measured on household members. I have my doubts that the persons_id
within a household is not unique. Is there a way I can "mass-check" all
20 variables between members of the same households to determine duplicate
records. I thought of the following:
sort hhid persons_id
for var V1-V20: gen DX=X[_n]==X[_n-1]
quietly by hhid: egen DSUM=rsum( DV1. .... DV20)
quietly by hhid: drop if DSUM[n]==20
Does that make sense!
Many thanks for your thoughts in advance...
Amani
