1. A method to determine statistical dominance point descriptors for a multidimensional data set, the method comprising:

  • determining, using a programmable processor, a first joint dominance value for a first data point in the multidimensional data set, each data point in the multidimensional data set comprising a multidimensional value, each dimension of the multidimensional value corresponding to a different measurement of a physical event, the first joint dominance value corresponding to a number of data points in the multidimensional data set dominated by the first data point in every dimension;

    determining, using the programmable processor, a first skewness value for the first data point, the first skewness value corresponding to a size of a first dimension of the first data point relative to a combined size of all dimensions of the first data point; and

    combining, using the programmable processor, the first joint dominance value and the first skewness value to determine a first statistical dominance point descriptor associated with the first data point.
