Testing Nested Models

[jinelcrimp8]

Hi all

My statistics knowledge is fairly basic so forgive me if this is a simple question. I am using a cumulative logit model and am trying to test whether the addition of a 2nd level improves the fit of the model. Previously I have used the likelihood ratio test, but MLwiN doesn't produce this for logistic regression.

What test should I use to work this out and how do I do this in MLwiN?

Thanks
