To estimate certain system data (second system data) by using the other system data having some relationship (first system data).SOLUTION: A fluctuation tendency in order of positions of measured values is calculated by obtaining a sudden change position at which a measured value is suddenly and relatively changed in each piece of first system reference date data, which is data of a reference date of first system data obtained by measuring a first physical amount, first system target date data, which is data of a target date of the first system data, and second system reference date data, which is data of a reference date of second system data obtained by measuring a second physical amount. Thereafter, a fluctuation tendency of the second system data on the target date is estimated according to a fluctuation tendency of the second system reference date data based on a difference between the fluctuation tendency of the first system reference date data and the fluctuation tendency of the first system target date data.SELECTED DRAWING: Figure 3

    【課題】何らかの関係性を有する他の系統データ(第1の系統データ)を用いて、ある系統データ(第2の系統データ)を推定すること。【解決手段】第1の物理量を計測した第1の系統データの基準日のデータである第1の系統基準日データ、第1の系統データの対象日のデータである第1の系統対象日データ、第2の物理量を計測した第2の系統データの基準日のデータである第2の系統基準日データ、のそれぞれについて、計測値が相対的に急変している急変位置を求めることで、当該計測値の位置順の変動傾向を算出する。そして、第1の系統基準日データの変動傾向と第1の系統対象日データの変動傾向との差異に基づいて、第2の系統基準日データの変動傾向から、対象日における第2の系統データの変動傾向を推定する。【選択図】図3
