larsenAone

larsenAone,Partition,Partition-method

Compute the measure of Larsen and Aone
$$
\frac{1}{|\cal{P}|} 
\sum_{C \in \cal{P}}{\max_{D \in \cal{Q}}{\frac{2|C \cap D|}{|C| + |D|}}}
$$

Provides several measures ((dis)similarity, distance/metric,
correlation, entropy) for comparing two partitions of the same set of
objects. The different measures can be assigned to three different
classes: Pair comparison (containing the famous Jaccard and Rand
indices), set based, and information theory based.
Many of the implemented measures can be found in
Albatineh AN, Niewiadomska-Bugaj M and Mihalko D (2006)
<doi:10.1007/s00357-006-0017-z> and
Meila M (2007) <doi:10.1016/j.jmva.2006.11.013>.
Partitions are represented by vectors of class labels which allow a
straightforward integration with existing clustering algorithms
(e.g. kmeans()). The package is mostly based on the S4 object system.
