| Abstract: | A quantity based on the number of runs of matches between two lithological sequences is suggested as an alternative or a supplement to the coefficient of cross-association. It is shown that, in many practical situations, the proposed random variable can serve as a more sensitive indicator of nonrandom similarities between two such sequences. Formulas pertaining to its asymptotic properties under the assumption of independence are derived. |
