Note on Initial Misclassification Effects on the Quadratic Discriminant Function

Abstract

Initial misclassification can have serious effects on the error rate of the quadratic discriminant function. The effects are more serious for large initial misclassification rates, and equal misclassification rates in both groups do not alleviate the problem as in the equal covariance case.
