Troubleshooting
Problem
I wanted to use a SELECT IF command that deletes cases in SPSS on the basis of a lag function. Say, for example, that I wanted to delete duplicate ID cases in a data set. I used the following syntax: SELECT IF (id ne lag(id)). when I ran this, all my cases were deleted. If I filter the cases, they're all in the file and filtered as they should be. Why does the SELECT IF delete all my cases?
