Hey, I apologise in advance if I am posting in the wrong section.

I am having an issue with my regression, whereby it requires scaling all coefficients and the intercept by lagged assets. I am unsure how to do this using SAS. The problem lies with the intercept, I don’t know how to lag that (I can just divide the other variables by the lagged assets).

E.G.

Nominal Income (Y) = a(1/lagged assets) + b(revenue change/lagged assets) + c(Property, Plant and Equipment/lagged assets).

Any help would be appreciated.
