Subject: st: Generating numeric ids
Dear Statalisters,
I have a large panel dataset creators of which decided to encrypt the
participants IDs via some unknown algorithm to covert them (original
id numbers) into strings. I am stock trying to figure out how to
create unique numerical identifiers from these given that the data is
panel (in the long format). I provide a small example below. As always
your help is much appreciated.Thanks, Dmitriy
