摘要： A first time-series data set indicating first measured values obtained by a first device and a second time-series data set indicating second measured values obtained by a second device are obtained. First alignment is performed to convert the positions in the time domain of the first measured values belonging to a second period, based on the first measured values belonging to a first period. Second alignment is performed to convert the positions in the time domain of the second measured values belonging to the second period, based on a relationship between positions before and after the conversion. Correlation analysis is performed between third and fourth time-series data sets respectively obtained by the first and second alignment. The existence or absence of an inclusion relationship in which the second measured values contain a component of the first measured values is determined based on the correlation analysis result.
