Abstract
An index calculation unit calculates a periodicity determination index for determining the presence of periodicity on the basis of the differential between each segment of the frequency distribution of input numerical data and a frequency distribution in accordance with a baseline distribution provided ahead of time. A determination unit uses the periodicity determination index calculated by the index calculation unit to determine the presence of periodicity including one or more periodic components present in the numerical data.
