Calculation of Smith’s Mean Measure of Divergence for Intergroup Comparisons Using Nonmetric Data

The Mean Measure of Divergence (MMD) is a formula that converts a battery of trait frequencies into a numerical value such that the more dissimilar two samples are, the greater the value. This measure of phenetic distance was developed by the statistician Cedric A. B. Smith and has become popular am...
