Introduction: spatial effects ESDA identifies: n Spatial distributions. n Atypical locations. n Forms of association: spatial autocorrelation . n Structures in the geographic space: spatial heterogeneity . 3 4 1. Introduction: spatial effects (ii) n Existence of a functional relationship between what happens at one point in space and what happens elsewhere. n Two causes: measurements errors and spatial interactions. n Space as explanatory of human behavior: distance matters. n What is observed at one point is determined by what happens elsewhere in the system.
