An information processing apparatus that tests independence among a multiplicity of variables includes an execution section and a determination section. The execution section executes a test for conditional independence between two variables in a graphical model that are at least not independent in the case where a condition variable serving as a condition for independence between the two variables is provided on a path between the two variables. The determination section determines whether or not a V-shaped structure is present on a path between the two variables, the V-shaped structure being a graph structure in which first and second variables that are independent are each not independent of a third variable. The execution section does not execute a test for conditional independence between the two variables in the case where the condition variable is provided only on a path determined to have the V-shaped structure.
