Expansion Method, Dependency, and Multimodeling

Abstract

The body of this chapter consists of three sections: expansion method, dependency, and multimodeling. In the first section the expansion method is defined, discussed, illustrated by an example, and pertinent literature items are briefly showcased. In the second section it is shown that when an estimated model’s residuals show significant spatial dependency the expansion method can provide a course of action to remedy this dependence. In the third section an expansion based multimodeling approach to remedying spatial dependence is presented and demonstrated. The themes addressed in these sections are briefly outlined hereafter.
