DEVICE, METHOD, AND PROGRAM FOR DETERMINING INPUT ATTRIBUTE CONDITION, DATA ANALYZER, DATA ANALYSIS METHOD, AND DATA ANALYIS PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a device, a method, and a program for determining input attribute conditions, a data analyzer, a data analysis method, and a data analysis program, that make data analysis efficient. PSOLUTION: The device for determining input attribute conditions and the data analyzer are provided with; a frequency calculation part 6 for calculating proportions of data of which the input attributes are equal to or smaller than each of all numerical values which input attributes take in an analysis data group to be classified into first and second data groups dependently upon values of output attributes, in the first and second data groups as first and second frequencies; a frequency cumulative difference calculation part 7 for calculating the difference value between the first and second frequencies with respect to each of all numerical values which input attributes take; a threshold determination part 130 for taking a numerical value giving a maximum difference value out of numerical values which one input attribute takes, as a threshold for the input attribute and determining at least one threshold corresponding to at least one input attribute; and an input attribute condition determination part 111 for determining an input attribute condition for dividing the analysis data group into two so that the first and second data groups are collected respectively, on the basis of the threshold.
