IDENTIFYING PATTERNS OF SIGNIFICANCE IN NUMERIC ARRAYS OF DATA
First Claim
1. An article of manufacture, comprising:
- a machine readable storage medium comprising instructions which when executed by a machine cause the machine to perform operations comprising;
receiving a data set;
based on a plurality of data patterns, determining relative pattern significance factors for the plurality of data patterns, the determining comprising;
if the pattern type is an outlier pattern, calculating a percentage change of an identified outlier from a median;
if the pattern type is a step change pattern, calculating a percentage of a step change between a last value of a step and a first value preceding the step, wherein the step corresponds to an outlier in a first difference on the data set; and
if the pattern type is a trend pattern, calculating a degree of freedom factor;
accepting a fitted curve approximation based on the degree of freedom factor;
calculating a percentage change from a start value on the fitted curve to a end value on the fitted curve; and
returning a ranked list of the pattern types based on their corresponding relative pattern significance factors.

Abstract
Disclosed is a computer method and system for identifying significance of patterns across a plurality of data patterns, which involves identifying pattern types of the plurality of data patterns, determining a relative pattern significance factor to compare the pattern types. Determining the relative pattern significance factor further involves calculating a percentage change of an identified outlier from a median for a outlier pattern, calculating a value of a step change as a percentage of a last value of a step preceding the step change for a step change pattern and calculating a percentage change from a start value on the fitted curve to an end value on the fitted curve for a trend pattern. A ranked list of the pattern types are returned based on their corresponding relative pattern significant factors.
