Abstract
In 1987, Hubert and Arabie proposed a randomization test of hypothesized order relations, and this has been operationalized in the Microsoft FORTRAN RANDALL program. This program enables the evaluation of the fit of any pattern model to a data matrix of similarities or dissimilarities. The exact probability of the model-data fit exceeding chance (as defined by a random relabeling of the rows and columns of the data matrix) is provided. This program is especially valuable in the evaluation of circumplex models of data as found in color perception, vocational interests, and interpersonal behavior.
