Dear Stata list,
I have the following problem: I have data where people had been asked
to provide their name and the name of their twin.
I would like to generate an identifier for each twin pair. How can I
do that without really search for each name? I have a couple of
hundred people.
My data looks like this:
name / Twin name / TwinID
Helena Harris / Joanne Moore / 1
Kevin Dedman / Tom Dedman / 2
Freya Lamb / Sandra Scott / 3
Sandra Scott / Freya Lamb / 3
Tom Dedman / Kevin Dedman / 2
Joanne Moore / Helena Harris / 1
How can I generate the variable TwinID? Can anyone help?
Thank you very much.
Maria
