Analyzing model of Business Ownership

[yael]

Hello

I have probably a silly question but I want to be sure that I understand this point.

I want to compare between businesses ownership in England to businesses ownership in USA. I beleive that USA have high performance than in England and the business ownership contributes that it will happen.

My code is simple:

proc glm data=sasuser.sasfile1;

class firmno sector year industry;

model roa = usaown salesGro RDAssets  LTassets LNAssets cAPAXASS DIVASSETS **bleep**efound BETA industry year

/solution;

run;

where ROA is the profit/assets and usaown is the business ownership % of the firms in USA (in my data). The data is 2600 firm-year observations. My question is - Is this code OK or should I relate to England ownership too?

Thanks a lot!

First of all, you need to know what kind of model you want to build :   ANOVA ?

or rate estimate -- Poission Regression ?
