Multilevel homogeneity analysis with differential weighting
We extend the technique of homogeneity analysis and nonlinear principal components analysis to a multilevel sampling design framework. We also propose a model that differentially weights the groups of objects, and thus allows us to make within- and between-groups comparisons. A data set from the National Educational Longitudinal Study is used to illustrate the techniques introduced in this paper.
