My statistics knowledge is fairly basic

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

Discrete response models fitted via (R)IGLS in MLwiN are often compared using a Wald test. For details of how to do this test see the MLwiN manual, for example on pages 125, 131 and 138.
