Data processing system and data processing method

A data processing system that calculates a correlation variable between multiple variables, the data processing system comprising:

• 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;
• 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;
• and
• an input unit into which a threshold that is at a lower limit of the first correlation coefficient is input,
• wherein, based on the second correlation coefficient and the third correlation coefficient, the first determination unit determines whether or not there is a likelihood that the first correlation coefficient will exceed the threshold.
