METHOD AND SYSTEM FOR EVALUATING CORRELATION BETWEEN BRAND AND VEHICLE, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method capable of objectively, quickly and reliably evaluating the correlation between a brand and a vehicle. SOLUTION: This method evaluates the correlation between the brand and/or the vehicle on the basis of a factor obtained as a result of the factor analysis of a brand group and/or a vehicle group. When the factor score of each brand and/or each vehicle in each factor is expressed as a distance from the origin on a factor axis in a coordinates space in which a plurality of factors are respectively defined as axes and factor score = 0 is defined as the origin, the correlation evaluating method evaluate the correlation by taking the dimension θ of an angle formed between vectors or the angle θ and distance into consideration.
