Subject   st: Intraclass correlations for 2-way ANOVA?

I would like to calculate an intraclass correlation coefficient, to 
measure agreement between raters. I know that you can use the 
command "loneway" along these lines: 

loneway measurement rater 

...but I have measurements by the same group of raters on several
different objects (the objects being indentified by the variable "ID").
I want to use the two-way model: 

anova measurement id rater 

How would I calculate an ICC from the sums of squares given in the 
resulting ANOVA? 

Thankyou

Rena
