PURPOSE: To shorten the working time for a data analysis by squeezing down many items of a data base on an analysis item, selecting a rule for analysis to be used for an analysis and outputting the rule. CONSTITUTION: An analysis item convergence part 112 calculates the dispersion and correlation coefficient of inputted object data and displays them through the screen of an analysis item selection part 131. A rule generation part 113 combines conditions in the range of a maximum condition number and performs a calculation by defining the rate of 'reactive' data contained in the data compatible to a rule as density. A rule evaluation part 114 performs the calculation by defining the rate of 'reactive' data compatible to the rules in a rule output order as a cumulative covering ratio and displays the transition graphs of the cumulative convering ratio and the density on the screen of a rule selection part 133. When the display range of the rule is inputted, the discrimination ratio of each condition of the rules, the predictive values of the density by the integrated value of the discrimination ratio of each condition are comapred, the rule in which the integrated value is large is emphatically displayed and the conditions are displayed in the higher discrimination ratio order of each condition. |
