Correlator Analysis of Multiparticle Events
  A procedure for the evaluation of correlators of any order in a reasonable computer time is presented. Connection between correlators and fluctuations of the event mean values of observables is discussed. Extension of the procedure to event-by-event approach is suggested. The usefulness of the method is demonstrated using the events simulated within various models of multipaticle production.
