STATISTICAL OPTIMIZATION INTEGRATION DEVICE AND STATISTICAL OPTIMIZATION INTEGRATION PROGRAM

摘要

PPROBLEM TO BE SOLVED: To facilitate change of variables used for a model for use in a mathematical programming method. PSOLUTION: This statistical optimization integration device comprises an observation data storage section 11 for storing observation data of each variable, a variable selection section 16 for selecting an objective variable and explanatory variable from the variables stored in the observation data storage section 11, a statistical analysis section 17 for estimating a relational expression between the objective variable and explanatory variable by statistical analysis using the observation data of the objective variable and explanatory variable, an analysis means (phrase analysis section 18 and syntax analysis section 20) for developing the estimated relational expression and determining the explanatory variable, a variable group as a combination of the explanatory variable and a multiplication or division operator and its variable, or a coefficient of the variable group, and a labeled display section 23 for displaying the determined variable, the variable group and its variable, or the coefficient of the variable group.
