Method, apparatus, and program for detecting the correlation between repeating events
First Claim
1. A detecting apparatus that detects a degree of correlation between first events and second events repeatedly occurring in an observed apparatus, comprising:
- an acquiring unit that acquires second event count values, each second event count value indicating a number of second events occurring during a first period, each first period being a period between a first event and a next first event;
a measuring unit that measures an observed number of each second event count value derived from the number of times the second event count value is observed; and
a calculating unit that calculates a strength/degree of correlation between the first events and the second events based on the observed number of each second event count value within a pre-established calculation formula in which the observed number of each second count value is evaluated;
with one or more other values;
within a measurement period; and
/or against a pre-determined threshold;
wherein the acquiring unit further acquires first event count values, each first event count value indicating a number of first events occurring during a second period, each second period being a period between a second event and a next second event;
wherein the measuring unit further measures an observed number of each first event count value derived from the number of times the first event count value is observed; and
wherein the calculating unit calculates the strengthldegree of correlation based on the observed number of each second event count value and each first event count value.

Abstract
A detecting apparatus detects the degree of correlation between first events and second events repeatedly occurring in an observed apparatus includes an acquiring unit that acquires second event count values each indicating the number of second events occurring during each first period between each first event and the first event next thereto. A measuring unit measures an observed number of each second event count value derived from the number of times the second event count value is observed. A calculating unit calculates the degree of correlation between the first events and the second events based on the observed number of each second event count value.
