Abstract
The paper examines the potential for combining a spatial statistical methodology
– Geographically Weighted Regression (GWR) – with geovisual analytical
exploration to help understand complex spatio-temporal processes. This
is done by applying the combined statistical – exploratory methodology
to a simulated data set in which the behaviour of regression parameters
was controlled across space and time. A variety of complex spatio-temporal
processes was captured through space-time (i.e. as spatio-temporal) varying
parameters whose values were known. The task was to see if the proposed
methodology could uncover these complex processes from the data alone.
The results of the experiment confirm that the combined methodology can
successfully identify spatio-temporal patterns in the local GWR parameter estimates
that correspond to the controlled behaviour of the original parameters.
