Dear all,
I would like to know if I can compare by a significance test 2 models
with different kind of parameters. Perhaps I am wrong but I think that
we can only compare 2 models if one is a sub model of the other.
The literature you seek is on 'non-nested' models. Here is a start:
Bradley Efron
Comparing non-nested linear models
J. of the Amer. Stat'l. Assn.

Google is your friend. Try 'non-nested test' and 'non-nested model'
and you will get many hits.
