Multiple regression analyzer and multiple regression analysis method

摘要

To provide a multiple regression analysis device capable of accurately performing multiple regression analysis.SOLUTION: A multiple regression analysis device 100 includes a determination unit 118, a division unit 120, an analysis unit 122, and a regression equation acquisition unit 124. The determination unit 118 determines, as stratified explanatory variables, explanatory variables that are effective as parameters when stratifying a plurality of datasets among a plurality of explanatory variables. The division unit 120 divides the plurality of datasets into layers by using the stratified explanatory variables. The analysis unit 122 performs multiple regression analysis on each of the divided groups of the datasets. The regression equation acquisition unit 124 acquires an integrated multiple regression equation in which the results of multiple regression analysis are integrated.SELECTED DRAWING: Figure 2
