Compare between groups

Hello,

 

I need your help in comparing between groups.

 

I have 3 groups:

 

  • Firms that were founded on 1930 (dummy variable FF with 1 for the relevant firm)
  • Firms that were founded on 1970 (dummy variable FNF with 1 for the relevant firm)
  • Other firms

 

The dependent variables is ROA and the code is:

 

proc reg data=sasuser.sasfile010916;

model roa = ff fnf Lnsalesgro lnassets RDAssets;

run;

 

If, for example, the coefficient of FF is 0.08 (significant) and for FNF is 0.01 (significant). That means that firms that were founded on 1930 have higher rate in 8% in ROA in relate to the 2 other groups?

 

Thanks for your help, it always great!

 

Yael

Re: Compare between groups

An estimate of .08 for the coefficient of FF means that in your model, an increase of 1 in FF yields an increse of .08 in ROA holding all other independent variables in your model fixed.
