CORRELATION DETERMINATION PROGRAM, CORRELATION DETERMINATION METHOD, AND CORRELATION DETERMINATION DEVICE

摘要

A correlation determination program for causing a computer to execute a process including calculating a time interval between an occurrence time of one of first type events and an occurrence time of each of second type events based on information including the occurrence times of the first type events and the second type events, for each of the first type events; comparing, for each of ranges of values relating to the time interval, a first rate of the number of time intervals within the range among a set of time intervals to a size of the range and a second rate of the number of time intervals outside the range among the set to a size of a range obtained by excluding the range from the predetermined time; and determining presence or absence of a correlation between the first type and second type events.
