I appretiate your input to this discussion. Do you know of a reference 
to your statement above? 

I had actually used the test-statistic which in my case is r-squared 
to compare them. This is in my view was adequate but I also think it 
is more convincing to say something about the p-values (difficulties 
in computing them, and hence the rationale of solely using the test-
stat).
