In a two-group discriminant analysis problem using regression, why is the midpoint cut-off value used to determine group classification?
A) Because the value minimizes the absolute misclassification error.
B) Because the value minimizes the probability of misclassification error.
C) Because the value represents an equal division between the groups.
D) Because the value incorporates problem specific knowledge.
