Rand Index {EMCluster} | R Documentation |
This function returns the Rand index and the adjusted Rand index for given true class ids and predicted class ids.
RRand(trcl, prcl, lab = NULL)
trcl |
true class ids. |
prcl |
predicted class ids. |
lab |
known ids for semi-supervised clustering. |
All ids, trcl
and prcl
, should be positive integers and
started from 1 to K, and the maximums are allowed to be different.
lab
used in semi-supervised clustering contains the labels which
are known before clustering. It should be positive integer and
started from 1 for labeled data and 0 for unlabeled data.
Return a Class RRand
contains Rand index and adjusted
Rand index.
