Abstract Two coefficients are proposed for measuring the
extent of overlap in distributions as a direct function of the
variance between the arithmetic means (»disco« and »odisco

Two coefficients are proposed for measuring the
extent of overlap in distributions as a direct function of the
variance between the arithmetic means (»disco« and »odisco
«). They are designed to answer such questions as: »Given
the value of a numerical variable x, to which population
should an individual be assigned so that minimum error
would be incurred?« This is just the reverse of the question
addressed by ANOVA. These coefficients are shown to be
analytic in x and they are related to. Pearson's eta and
Fisher's F. Extensions of these coefficients (designed for
univariate, one way discrimination) to k-way and multivariate
discriminant analysis and measurement of »interaction
« are suggested.... view less
