I forgot to mention:
11111 is the very last observation at the end of the dataset. The
extension should only be done to this very last observation.
Example:
Number Year Other variable of interest
77777 1975 9
22222 1972 8
11111 1999 5
Extension to:
Number Year Other variable of interest
77777 1975 9
22222 1972 8
11111 1999 5
11111 2000 .
11111 2001 .
11111 2002 .
11111 1998 .
11111 1997 .
11111 1996 .
All the observations before should not be extended. They stay exactly
the same. Only the very last one (11111 in our case).
