Gets the vector of cophenetic distances between all possible object pairs.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public DoubleVector CopheneticDistances { get; }

Public ReadOnly Property CopheneticDistances As DoubleVector
	Get

public:
property DoubleVector^ CopheneticDistances {
	DoubleVector^ get ();
}

member CopheneticDistances : DoubleVector with get

Property Value

DoubleVector

Remarks

The cophenetic distance between two objects is defined to be the intergroup distance when the objects are first combined into a single cluster in the linkage tree.
The format is the same as the distance vector returned by Distances.
The correlation between the original Distances and the CopheneticDistances is sometimes taken as a measure of appropriateness of a cluster analysis relative to the original data:

Copy

ClusterAnalysis ca = new ClusterAnalysis( data );
double r = NMathFunctions.Correlation( ca.Distances, ca.CopheneticDistances );
