Patent ID: 7974800

Claim:
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.
