[R-lang] Re: Determining whether a model fits a second data set

[Daniel Ezra Johnson]

That's a great question. I'm jumping in without having a great answer.

1) Does anyone know if you can do something like.... deviance per
observation or something else that would be comparable across models,
maybe only at the level of "this data fits the model better than that
data".

2) I think simulations would be very useful for answering all the
questions you raise here:

I could talk more off list about constructing such simulations but
it's not very hard.
