st: Poisson Rates

[jasonm@ucla.edu]

I created a poisson model with the number of injuries as the depedent  
variable and age, experience and age*experience as the predictors.
Age and experience are categorical variables. We have a lot of people  
with the similar ages and experience levels so I'm categorizing age  
and experience into 1 year intervals.
My outcome is then the number injuries predicted for each of these  
age/experience groups.
I'm first plotting experience vs the number of predicted injuries by  
various 1-year age categories.
In order to turn the y-axis (counts) into rates can I divide each of  
these 1-year experience groups by the number of hours worked for that  
1-year experience group?
Thanks for your help.
