<p>PROBLEM TO BE SOLVED: To estimate a cause-effect relationship between multiple variables, on the basis of a conditional independence test, even when a categorical variable and a numerical variable are mixed in multiple variables.SOLUTION: A discretization section discretizes at least one numerical variable on the basis of at least one categorical variable, when the categorical variable and the numerical variable are included in at least two dependent variables in a graphical model and a set of conditional variables serving as conditions of independence between the two variables, and a test execution section executes a test for conditional independence between the two variables by using the categorical variable and a discrete variable which is obtained by discretizing the numerical variable. This technique can be applied to an information processing apparatus capable of estimating a cause-effect relationship between variables.</p> |
