Hello everyone,
Is there a lag like function can get reversed lag without merging tables?
currently we have lag1(var),lag2(var).......,can we do something like lag(var,-1),lag(var,-2)......? this avoid merge tables.
Thanks!
If by reverse lag you mean look ahead, I don't think so. But it's quite easy, see: http://www.sascommunity.org/wiki/Look-Ahead_and_Look-Back

If you are able, you could sort in the reverse way and use the lag function to get the "reverse" lag.
