nearestneighbour analysis
nearestneighbour analysis(nearestneighbour measure) A method for testing the pattern of distribution of individuals. The mean nearestneighbour distance for all, or for a random sample of, individuals in a given area is compared with the expected mean distance if the same individuals were randomly distributed throughout the area. The ratio of the two mean values (R) is a measure of the departure from randomness, and may be tested for statistical significance. The value of R = 1 indicates randomness; R = 0 indicates maximum aggregation; and R = 2.149 indicates maximum possible spacing (i.e. a hexagonal pattern).
