A differential time series generation unitgenerates a difference time series between a value of an objective time series and a prediction value of the objective time series calculated based on a value of the first explanatory time series. An effect degree calculation unitcalculates, based on second explanatory time series among the plurality of explanatory time series and the difference time series, an influence degree of each of the second explanatory time series on a value change of the difference time series.
