The Recognition Taguchi (RT) method, which is one of the techniques used in the MT system, is a method in which sensitivity and S/N ratio are obtained from multivariate data using the standard S/N ratio, and then pattern distances are calculated usillg 2-row-by-2-column variance and covariance matrixes with the sensitivity and the S/N ratio used as items. In the RT method, as the S/N ratio and sensitivity obtained from the original data are used to calculate distance, the result is not affected by the quality of the data, and there are few constraints on the analysis. In this study, distances were calculated by this method from component pattern data of the Atractylodes lancea rhizome, which is one of the raw materials of Kampo medicine. Results obtained from the conventional calculation of the distances from two items were compared with results when distances were calculated using additional statistics.
