Subject: st: Identifying unique values within duplicate IDs
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
