RSKC (version 2.4.2)

CER: Classification Error Rate (CER)

Description

Compute the classification error rate of two partitions.

Usage

CER(ind, true.ind,nob=length(ind))

Arguments

ind

Vector, containing the cluster labels of each case of a partition 1.

true.ind

Vector, containing the cluster labels of each case of a partition 2.

nob

The number of cases (the length of the vector ind and true ind)

Value

Return a CER value. CER = 0 means perfect agreement between two partitions and CER = 1 means complete disagreement of two partitions. Note: 0 <= CER <= 1="" <="" dl="">
