Statistics

A pairwise agreement measure between two partitions

In statistics the Rand index measures the agreement between two partitions of the same set of objects (for instance a clustering against a known labelling) by counting the pairs of objects treated the same way (together in both, or apart in both) and dividing by all pairs, giving 1 for identical partitions. Rand's 1971 Objective criteria for the evaluation of clustering methods introduced the index, later adjusted for chance as the adjusted Rand index. The referent is a pairwise partition-agreement statistic bounded in [0,1], named after W. M. Rand, with no connection to a strip of leather in a boot.[1]

Unit
The proportion of object pairs on which two partitions agree
Recovery means
Not applicable
Measured by
Computed from the pair-counting contingency of two partitions; often reported chance-adjusted
