Dear all,

I'm trying to determine the degree of conservatisme
In order to do that I want to use the basu measure of conservatism with the formula NI=b0+b1NEG+ b2RET+ b3RET*NEG.
I have over 68.000 observations,each observation has a unique company code and fiscal year.
I would like to run the regression for each observation and capture the b3 als a sort of ranking of conservatism.

Does anybody know how I can do that?

The command regress NI NEG RET RET*NEG only give me a b3 for the entire set.
But iI would like the know the b3 for each observation.


Is this posible?

Thank you for your help.

Kinds regards
Kimberley
