Hello everyone.
I have panel data, and I have some individuals who have multiple observations in the same year.
What I want to do is that I want to keep the last observation of those individuals with multiple observations in the same year.
Visually, I want something like this… (I thought this would show better what I wanna do)
Id data year -> Id data year
1 2 2009 1 3 2009
1 3 2009 1 2 2010
1 2 2010 2 1 2009
2 1 2009 2 3 2010
2 2 2010
2 3 2010
I was trying to use command like: "Data …. ; Set ….; by ID year; if last.ID; run;", but this would only leave last observation of the individual of the last year (assuming that I sorted by ID and year) and erase the previous year. I was wondering if you have a suggestion or idea to this issue..
Thank you very much for your help!
Almost there, assuming correct sort order:
Data …. ; Set ….; by ID year; if last.Year; run;",
