The division unit divides the plurality of data sets for each layer using the stratification explanatory variable. The analysis unit performs a multiple regression analysis on each of groups of the plurality of data sets that have been divided. The regression equation acquisition unit acquires an integrated multiple regression equation in which results of the multiple regression analysis are integrated.
