IndexPartitionMinimumCentroidLinkage Method

Computes the minimum centroid linkage among parts in the given partition of the specified data.

Namespace: Novacta.Analytics
Assembly: Novacta.Analytics (in Novacta.Analytics.dll) Version: 2.0.0

Syntax

public static double MinimumCentroidLinkage(
	DoubleMatrix data,
	IndexPartition<double> partition
)

Public Shared Function MinimumCentroidLinkage ( 
	data As DoubleMatrix,
	partition As IndexPartition(Of Double)
) As Double

public:
static double MinimumCentroidLinkage(
	DoubleMatrix^ data, 
	IndexPartition<double>^ partition
)

static member MinimumCentroidLinkage : 
        data : DoubleMatrix * 
        partition : IndexPartition<float> -> float

Parameters

data: Type: Novacta.AnalyticsDoubleMatrix
The data whose rows represent the available observations.
partition: Type: Novacta.AnalyticsIndexPartitionDouble
The data partition to evaluate.

Return Value

Type: Double
Returns the minimum value of CentroidLinkage over the pairs of clusters corresponding to parts in partition.

Exceptions

Exception	Condition
ArgumentNullException	data. -or- partition is null.
ArgumentException	A part in partition contains a position which is not valid as a row index of data.

Remarks

Each column of data is associated to one of the variables under study, while its rows are associated to the individuals. The partition is intended to define parts which contains row indexes valid for data.

This method applies Euclidean distances.
