%description
Implements an efficient O(n) algorithm based on bucket-sorting for fast
computation of standard clustering comparison measures. Available measures
include adjusted Rand index (ARI), normalized information distance (NID),
normalized mutual information (NMI), adjusted mutual information (AMI),
normalized variation information (NVI) and entropy, as described in Vinh
et al (2009) <doi:10.1145/1553374.1553511>. Include AMI (Adjusted Mutual
Information) since version 0.1.2, a modified version of ARI (MARI), as
described in Sundqvist et al. <doi:10.1007/s00180-022-01230-7> and simple
Chi-square distance since version 1.0.0.
