Patent ID: 7552105

Claim:
A computer-readable storage medium storing an importance degree calculation program allowing a computer to execute operations calculating importance degree from an instance set and an explanatory variable, comprising: a section generation step that receives, as an input, an instance set and an explanatory variable and uses the instance set to divide the explanatory variable into a plurality of sections to obtain a section set; a neighborhood instance set extraction step that extracts, using the instance set, from across all the obtained sections a neighborhood instance set of each section in which a number of instances is greater than a neighborhood instance number threshold, stores the extracted neighborhood instance set in a neighborhood instance set database, and outputs the extracted neighborhood instance set from the neighborhood instance set database; an objective variable distribution calculation step that calculates an objective variable distribution from the output extracted neighborhood instance set of each section extracted by the neighborhood instance set extraction step; an importance degree calculation step that calculates importance degree of each section from the obtained objective variable distribution in each section obtained by the objective variable distribution calculation step and instance set; and an importance degree list display step that displays a list of the calculated importance degrees.
