Abstract
The technique of geographically weighted regression (GWR) is used to
model spatial ‘drift’ in linear model coefficients. In this paper we extend the ideas of GWR
in a number of ways. First, we introduce a set of analytically derived significance tests
allowing a null hypothesis of no spatial parameter drift to be investigated. Second, we
discuss ‘mixed’ GWR models where some parameters are fixed globally but others vary
geographically. Again,models of this type may be assessed using significance tests.Finally,
we consider a means of deciding the degree of parameter smoothing used in GWR based
on the Mallows C
p
statistic. To complete the paper, we analyze an example data set based
on house prices in Kent in the U.K. using the techniques introduced.
