st: Merging using the best match from a set of variables
Dear statalist users,
I have a couple of datasets that I am trying to merge. The problem is that
there is no unique identifier that can easily help me merge the observations
from the two datasets. Is there a way of merging the datasets such that if
two observations match in "most" of the variables then it's a match?
For example, if observation3 (dataset1) matches with observation2 (dataset2)
in var1, var2 and var3 but not var 4 nor var5, and if observation1
(dataset1) matches with obs2 only in var3 and var5 then, obs3 (from
dataset1) - and not observation1- should be merged with obs2(from dataset2).
I hope my explanation is not very confusing...
Thanks for your help!
