A likelihood ratio test that compares two nested models can be computed when the models are fit by maximum likelihood. Two models are nested when one model is a special case of the other so that one model is considered the full model and the other is a reduced model.

WebWhen the full model has exactly one more term than the reduced model, we can use a t-test. E.g., testing the Interaction model E(Y) = 0 + 1x 1 + 2x 2 + 3x 1x 2; against the First order model E(Y) = 0 + 1x 1 + 2x 2: H 0: \reduced model is adequate" is the same as H 0: 3 = 0.
