Regressing using scaling

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.

hi,

Assuming you have a variable at_lag which is lagged assets, then just divide 1 by lagged assets: one_at = 1 / at_lag

See this post how to get lagged/leads: http://www.wrds.us/index.php/forum_wrds/viewthread/164/

best regards,

Joost
