Abstract
A data processing system that calculates a correlation coefficient between multiple variables includes a storage unit in which a table in which multiple correlation coefficients are stored is stored, a first selection unit that makes a selection to determine whether or not calculation of a first correlation coefficient that is a correlation coefficient between a first variable and a second variable is indispensable, a second selection unit that selects a third variable which is a variable that results from storing in the table a second correlation coefficient that is a correlation coefficient representing a relationship with the first variable, and a third correlation coefficient that is a correlation coefficient representing a relationship with the second variable, and a first determination unit that determines whether or not the calculation of the first correlation coefficient is indispensable, based on the second correlation coefficient and the third correlation coefficient.
