I’ve been trying to use the extract system and the activity-level data to create activity-level variables, the same way that i use the person-level data to create variables, but it doesnt seem to work the way I think it should.
is there a way to do this in the extract system, or does it all need to be done in SAS?
(like, can i do something like this with the extract: if activity code=10000-19999 then DUMMYACTVAR=1)?
thanks for any help, guys!!!
