calc.cluster.comparisons {clustord} | R Documentation |
Calculate comparison measures between two sets of clustering results
Description
Given two sets of posterior probabilities of membership for clusters, calculate three measures to compare the clustering memberships.
Usage
calc.cluster.comparisons(ppr1, ppr2)
Arguments
ppr1 |
Posterior probabilities of cluster membership, named |
ppr2 |
Posterior probabilities of cluster membership from a different
clustering run, which will be compared to |
Details
The three measures are the Adjusted Rand Index (ARI), the Normalised Variation of Information (NVI) and the Normalised Information Distance (NID).
The three measures are documented in
Value
A list with components:
ARI
: Adjusted Rand Index.
NVI
