Lagged Variables for a Linear Model

[IdanE]

I'm making a linear model and I want to include lagged variables in it. It should be something like   Y= B0 + B1X1 + B2X2 + B3Y(i-1) + B4Y(i-7) + B5X1(i-1) + B6X1(i-2).

Does anyone know how I can set this up in Enterprise Guide?

Thanks!

If your lags are in different (prior) records, then you are going to have to write data step code to create them.  The data transformations in EGuide use PROC SQL.  SQL is "memoryless" and does not support the LAG function.
