I have a few parameters that are related (let's call them X1 and X2), and I want to use whichever one will provide the strongest model. The model has many other parameters. Would I simply be able to compare the AICc of these two models?
Model using X1:
Y ~ X1 + X3 + X4 + X5 + X6
Model using X2:
Y ~ X2 + X3 + X4 + X5 + X6
This is confusing me as I'm not sure what other parameters will ultimately belong in the "correct" model. Ultimately, X3, X4, etc. may be thrown out. So would I want to test this with potentially "bad" parameters?
