Hello Statalist scholars,
I am trying to generate a variable that will indicate missing BEFORE FIRST YEAR of OBSERVATION and missing AFTER FIRST YEAR of OBSERVATION.
Here is a sample of the data:
ID Y1 Y2 Y3 Y4 Y5 Y6 Y7
1 . . x x x x x
2 . x . x x x x
3 . . x x . x x
4 . x . x x . x
5 x x . x x x .
Any advice is very much appreciated!
Thank you so much for your time!
Regards,
RB
