Abstract : This note is a continuation of the work presented in Technical Note No. 4 (AD-638 493). In Section 1 of this note an investigation is made as to whether a variable should be included in or rejected from the linear discriminator (pattern recognizer) when the requirement is that the inclusion of a variable should give a fixed percentage increase to the squared distance. (In other words, inclusion of a variable should result in decreasing the probability of misclassification by a fixed amount.) In Section 2, the effect of positive and negative correlations of the variables in the discriminator is investigated. The investigation in Section 2 provides insight for the acceptance or rejection of a variable for discrimination. (Author)
