- The default cutoff value in the two-class classifier (i.e., C1/C2) is 0.5. Thus, if the probability of a record being a class C1 member is greater than 0.5, that record is classified as C1. It is possible to use a cutoff that is greater or lower than 0.5. In general, lowering the cutoff value will result in a decrease (no change) in the classification error rate for records that are truly C1. Note that is not an overall error rate.
