Measurement of patterns
These tests are used to measure whether a pattern exists and what type of
pattern it might be.
This involves comparing the observed spacing of a set of points and the spacing
that would be expected if the pattern had been random. This technique relies on
measuring the distance between neighbouring points usually on a map. The
observed spacing is expressed as the distance of all points from their nearest
neighbour in straight line measurement.
This technique is a measure of the degree of concentration of points. These curves
are used in economic geography, on data linked to areas and involve the comparison
of percentage frequencies.
