I am trying to merge some individual
(person) files using GHS data. For instance, suppose I merge different person
files using the 1983 wave. The merging procedure is as follows:
sort persno (person number in the household)
use c:\person83.dta (master data)
merge persno using c:\indivdl83.dta (where indivdl83 is the using data and
persno has been sorted before the indivdl83.dta data file is saved).
The merging of the two datasets is successful but Stata
reports the following errors: "variable persno does not uniquely identify
observations in the master data" and "variable persno does not uniquely
identify observations in the using data". I was wondering if you have
an answer to this problem.
