Abstract: A computer-readable recording medium contains a program for causing a computer to execute a process. The process includes executing multiple change point detection processes that detect respective change points of first time-series data with multiple granularities that are different in the width of a unit time. A first detection pattern that indicates the order of detection of the change points is stored in a storage part. Change points of second. time-series data subsequent to the first time-series data are detected with the different granularities. An output is generated that differs depending on whether a second detection pattern matches the stored first detection pattern. The second detection pattern indicates the order of detection of the change points of the second time-series data.
