Measuring Affinity of Distributions,

Abstract

In an earlier paper, Morisita discussed interspecific association (also called faunal affinity) and its measurement. One of his measures has become known as the Morisita-Ono index of faunal affinity and is routinely used in ecological studies. However, very little is known about the statistical properties of this measure or of certain competitors. The paper considers two other measures as well as the Morisita-Ono index, deriving some of their statistical properties. The approach taken is that of measuring the closeness, or affinity, of two distributions as discussed by Matusita. Only the case of discrete distributions is considered. The relative merits of the three measures are discussed, and an application is made to the comparison of species distributions at two sites. (Modified author abstract)
