lag calculation macro035 (2/3/2010 4:47:37 PM) comp.soft-sys.sas Has anyone else struggled with the lag function in SAS? The lag function often doesn't work in an intuitive manner in conditional statements, or if missing values are involved. Anyways, I wrote a short macro c... robertf

missing numerical values = - infinity?1236 (12/23/2009 8:52:28 PM) comp.soft-sys.sas Going into rant mode... I discovered a feature of SAS that I wish I had
known earlier: SAS will assign a value of *negative infinity* to missing
numerical values in logical statements.
So in the following ... robertf
