We report on a considerable improvement in the technique of measuring multiparticle correlations via integrals over correlation functions. A modification of measures used in the characterization of chaotic dynamical systems permits fast and flexible calculation of factorial moments and cumulants as well as their differential versions. Higher-order correlation integral measurements even of large multiplicity events such as encountered in heavy ion collisions are now feasible. The change from ordinary'' to factorial'' powers may have important consequences in other fields such as the study of galaxy correlations and Bose-Einstein interferometry.
