METHOD, APPARATUS, AND PROGRAM FOR DETECTING THE CORRELATION BETWEEN REPEATING EVENTS

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.
