DATA PROCESSING METHOD, ARITHMETIC UNIT AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a data processing method for making an effective analysis by treating both an attribute of a weighing type and an attribute value of a counting type. SOLUTION: This data processing method executes processing by an arithmetic unit by using the attribute value being a value acquired on the attribute of N pieces of objects having J pieces of attributes of the counting type and the weighing type. A CPU 25 formsσby executing an operation indicated by an evaluation expression (1) by using an optional matrix X and matrix ajwhen the attribute of the j (1≤j≪J) th is classified into Rjpieces. The CPU 25 specifies at least one of the matrix X and the matrix ajfor satisfying a prescribed converging condition by theσ. The CPU 25 plots at least one point of the objects and the attribute on a coordinate system of a P dimension on the basis of at least one of the specified matrix X and matrix aj.
