DEVICE FOR MULTIVARIABLE REGRESSION ANALYSIS

摘要

PURPOSE:To improve the efficiency of a regression analysis by preparing a regression analysis expression with interaction input, registering a large number of it after correction, deciding the regression expression optimum for the analysis of input data based on the expert knowledge rule by means of an expert system, and performing the regression analysis using the regression expression. CONSTITUTION:Plural regression expressions are prepared in advance with the interaction input in a computer terminal 10 by a regression expression preparation means, and these regression expressions are registered in a regression expression storage means 5. On the other hand, the actual data is inputted in an analysis execution means 6 at the time of the multivariable regression analysis, and the regression analysis is executed according to each regression expression registered in the regression expression storage means 5. In an expert system 8, the result analyzed by an analysis execution means 6 is evaluated by using the specialized knowledge rule to introduce the optimum regression expression. After the optimum regression expression is decided, the regression analysis is executed based on the once decided optimum regression expression against the same type of data. Thus, the analysis based on the optimum regression expression according to the input data can be performed.
