Hi,

I have a question regarding a method and test for comparing predictive power.

Specifically, it is quite common to have one sample of data and see 
which of two models better predict that sample (LR test, F-test, etc).

However, my situtation is a little different.  I have a single model 
and would like to see which of two samples is best explained by that 
model.  Are there standard procedures and tests for determining if the 
predictive power of this standard model is statistically different 
across the samples?

Many thanks in advance,
