Description

<p>The Recognition-Taguchi(RT) method is useful because, as itcollects items into the two variables β(sensitivity) and η(signal-to-noise ratio), a pattern distance can be obtained even when the number of original data items is greater than the number of unit space data items n, and because the dimensional reduction yields a solution even when the true values are unknown. In this study, however,the concept of the calibrated error variance proposed by Dr. Taguchi was applied. An attempt was made to calculate a general scale similar to the distance obtained by the RT method from the variation/variance ratio by use of analysis of variance, without calculating distances. Results matching the results of the RT method were obtained. In addition, it became clear that because analysis of variance is used, there is no limit on the number of items,which constrains matrix calculations, and the data can be treated in the same way as in the RT method.</p>
