Learning Objectives:
Describe real world applications where distance decay is an appropriate representation of the strength of spatial relationships (e.g., shopping behavior, property values)
Explain the rationale for using different forms of distance decay functions
Explain how a semi-variogram describes the distance decay in dependence between data values
Outline the geometry implicit in classical “gravity” models of distance decay
Plot typical forms for distance decay functions
Write typical forms for distance decay functions
Write a program to create a matrix of pair-wise distances among a set of points
Describe real world applications where distance decay would not be an appropriate representation of the strength of spatial relationships (e.g., distance education, commuting, telecommunications)
