One of the innovative approaches in the use of hierarchical linear models (HLM) is to use HLM for Slopes as Outcomes models. This implies that the researcher considers that the regression slopes vary from cluster to cluster randomly as well as systematically with certain covariates at the cluster level.

Proposed a definition of selection bias and studied the empirical relation between prediction bias and selection bias with respect to prominent social groups. Results show that, although the two biases are related, the relation is not isomorphic. It is mediated by the selection ratio, and for most selection ratios, it is only moderate. (SLD)

Proposes the use of the group overlap concept as a basis for determining effect size. Group overlap may be assessed via prediction of group assignment, using predictive discriminant analysis. The effect-size index proposed is that of improvement-over-chance "(I)" classification. Makes some suggestions for cutoffs of "I" values…
