Detection of Randomness in Sparse Data Set of Three Dimensional Time Series Distributions
Abstract
A two-stage method is provided for automatically characterizing the spatial arrangement among data points of a three-dimensional time series distribution in a data processing system wherein the classification of said time series distribution is required. The two-stage method utilizes Cartesian grids to determine the following: (1) the number of cubes in the grids containing at least one input data point of the time series distribution, (2) the expected number of cubes that would contain at least one data point in a statistically determined random distribution in said grids, and (3) an upper and lower probability of false alarm above and below said expected value utilizing a second discrete probability relationship to analyze the randomness characteristic of the input time series distribution.
