Partitioning variation in nonlinear models: MLwiN does not calculate the amount of variation at each level in nonlinear multilevel models unlike some other statistical packages. Due to the non-linear estimation procedure, the level 1 variance is no longer on the same scale as the level 2 variance, and so the terms at all levels do not add up to give the total variance for the model fitted. Therefore, the formula in a Normal response model cannot be used here.

There are a few methods for this. See http://www.bristol.ac.uk/cmm/software/s ... l#discrete for a discussion.
