The major concern for any research model, whether disproportionate or not, is the research question and how well that question is reflected by the model. Three "exact solutions" for disproportional situations, the hierarchial, unadjusted main effects, and fitting constant methods, are discussed in terms of the research question that each reflects, and examples demonstrating the most appropriate situation for using each solution are presented. The usefulness of a Chi Square Technique in differentiating between varying degrees of disproportionality and their effects on a Type I error is explained. (Author/MV)
