Abstract

A data analysis supporting apparatus according to an embodiment comprises a variable-type determining device, a variable-variation generating device, and a variable-contribution rate determining device. The variable-type determining device determines the type of each variable. The variable-variation generating device generates variations of each variable in accordance with the variable type determined and with a variable variation rule that defines a method of generating the variations of each variable of any type. The variable-contribution rate determining device calculates the rate at which the variations and analysis data contribute to the objective variable, and determines, from the rate, whether the variations should be used or deleted.

Claims

1. A data analysis supporting apparatus designed to generate variations of each of variables from analysis data having an objective variable and variables that are explanatory variables for the objective variable, thereby supporting the analysis of the analysis data, the apparatus comprising:

a variable-type determining device configured to determine the type of each variable;

a variable-variation generating configured to generate variations of each variable in accordance with the variable type determined and with a variable variation rule that defines a method of generating the variations of each variable of any type; and

a variable-contribution rate determining device which calculates the rate at which the variations contribute to the objective variable and determines, from the rate, whether the variations should be used or deleted.

2. The data analysis supporting apparatus according to claim 1, further comprising:

a variable-variation rule storing device configured to store the variable variation rule; and

a rule-changing device configured to change the variable variation rule stored in the variable-variation rule storing device, in response to a rule-changing instruction.
