Methods and apparatus to determine statistical dominance point descriptors for multidimensional data
First Claim
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.

Abstract
Methods and apparatus to determine statistical dominance point descriptors for multidimensional data are disclosed. An example method disclosed herein comprises determining a first joint dominance value for a first data point in a multidimensional data set, data points in the multidimensional data set comprising multidimensional values, each dimension 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 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 the first joint dominance and first skewness values to determine a first statistical dominance point descriptor associated with the first data point.

14. A tangible article of manufacture storing machine readable instructions which, when executed, cause a machine to at least:
-
store a multidimensional data set in a computer memory; determine 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, 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; determine 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; combine the first joint dominance value and the first skewness value to determine a first statistical dominance point descriptor associated with the first data point; and present the first joint dominance value via a graphical user interface. - View Dependent Claims (15)
