TIME-SERIES DATA PROCESSING METHOD RECORDING MEDIUM HAVING RECORDED THEREON TIME-SERIES DATA PROCESSING PROGRAM AND TIME-SERIES DATA PROCESSING DEVICE

摘要

The group generating unit 12 generates a plurality of groups composed of a plurality of time series data that change in the same manner based on the plurality of time series data 7. The normalization unit 13 performs linear transformation on the data included in the time series data in the group so that the maximum value of the median value included in the median time series data is 1 and the minimum value is 0 for each group. The anomaly calculating unit 14 obtains an average value of differences between data of the same time for all combinations of two time series data in a group for each group, and determines the maximum value of the obtained average values as an anomaly of the group. The ranking generating unit 15 generates the ranking of the group based on the anomaly of the group, and the result display unit 17 displays the screen including the ranking of the group.
