Two statistical measures, based on contingency tables, were compared in trying to reveal the periodic or quasiperiodic structure of a texture from its cooccurrence histogram: the chi /sup 2/ and the kappa statistics. Both are sensitive to periodicity, but the kappa statistic is clearly better in the sense that the chi /sup 2/ can attain high values for displacements quite different from the actual period, as long as the cooccurrence histogram shows a specific structure associating the two relevant variables. If periodicity is the property looked for, then statistical agreement, measured by the kappa statistic, is the property that will best reveal it.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
