METHOD FOR EXTRACTING MULTIPLE REGRESSION EQUATION

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently evaluating data obtained using a multivariate analysis technique and extracting an accurate multiple regression equation with a small man-hour.;SOLUTION: External data comprising a plurality of multiple regression equations obtained by performing multivariate analysis on a data group which are objective variables and explanatory variables of the objective variables in the multivariate analysis, and its evaluation data is acquired (step S1). Then, for each of the plurality of multiple regression equations, based on a predetermined multiple regression equation evaluation criterion, first evaluation which determines the adaptability of the multiple regression equations is performed (step S2). For each of the explanatory variables used for deriving the multiple regression equations which are determined to be adaptable in the first evaluation based on a predetermined explanatory variable evaluation criterion, second evaluation which determines adaptability as explanatory variables is performed (step S3). A multiple regression equation having the highest evaluation value in the second evaluation is extracted (step S4).;COPYRIGHT: (C)2010,JPO&INPIT
