Measurements of patterns
These are used to measure whether a pattern exists and what type of pattern it
might be.
Nearest neighbour
This compares the observed spacing of a set of points and the spacing expected if
the pattern was random. This technique relies on measuring the distance between
neighbouring points such as on a map. The observed spacing is expresses as the
distance of all points from their nearest neighbour in straight line measurement.
Lorenz curve
This technique is a measure of the degree of concentration between points, these
curves are used in economic geography, on data linked to areas and involve the
comparison of percentage frequencies.
