N,PairCoefficients-method

Instance of <a href="/link/?package=partitionComparison&version=0.2.5" paircoefficients'="" data-mini-rdoc="partitionComparison::"></a>'>PairCoefficients

It is defined as \(N = N_{11} + N_{10} + N_{01} + N_{00}\) which equals 
\(n \choose{2}\) with \(n\) the number of objects

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.
