Hi all!
I'm dealing with a large dataset that had some errors occur when data were being recorded. Although each ID should only
have one record, most of them have two. Anyway, I'm trying to get a list of IDs where the ID variable is a duplicate but
the values for a second variable (PHQ9 score) are different within the duplicate ID. Any advice would be greatly
appreciated.
Thanks,
Rebecca Sacks
