1. A method of analyzing a multidimensional system comprising the steps of:

  • acquiring a plurality of signals, each signal representing a corresponding channel that is associated with a different spatial location of the multi-dimensional system;

    generating a phase space representation for each channel as a function of the corresponding one of the plurality of signals;

    generating a signal profile for each phase space representation, each signal profile reflecting a rate of divergence of the corresponding phase space representation;

    choosing a selected predictor from amongst a plurality of possible predictors based on a level of entrainment of critical channel groups associated with each predictor;

    for the selected predictor, deriving a signal profile for one or more critical channel groups, each signal profile reflecting a level of correlation between the channels of each critical group; and

    characterizing the state dynamics of the multidimensional system as a function of the signal profile associated with at least one critical channel group.
