Re: lag calculation macro #4026 (2/3/2010 5:57:14 PM) comp.soft-sys.sas Thanks Joe! It's tempting to use macros or arrays in SAS when a simpler code works far more efficiently. Too bad there isn't a SAS guide that covers common pitfalls in SAS programming such as this. =20 From: ... RobertF

lag calculation macro022 (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

Re: missing numerical values = - infinity?0244 (12/23/2009 10:52:01 PM) comp.soft-sys.sas Thanks Mark, I agree that one must carefully tailor code to deal with
missing values in SAS or any language.
That's interesting that Stata sets missing values at positive infinity.
The R programming langua... RobertF
missing numerical values = - infinity?1207 (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
