Geary's C Autocorrelation Statistic
Description
Geary's c statistic is used to measure autocorrelation between areas within a region, as follows:
is a squared matrix which represents the relationship between each
pair of regions. An usual approach is set
to 1 if regions
and
have a common boundary and 0 otherwise, or it may
represent the inverse distance between the centroids of that two regions.
Small values of this statistic may indicate the presence of highly correlated areas, which may be a cluster.
