KMeansTData, TDataSumEvaluateDaviesBouldinIndex(FuncTDataSum, TDataSum, Double) Method

Evaluates the Davies-Bouldin-Index. The exponent q (see EvaluateDaviesBouldinIndex(FuncTDataSum, TDataSum, Double, Int32)) is set to 1, meaning that the mean Euclidean distance of the points to their respective centroid is used in the nominator.

Namespace: Altaxo.Calc.Clustering
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax

Copy
public double EvaluateDaviesBouldinIndex(
	Func<TDataSum, TDataSum, double> distanceFunctionOfClusterMeans
)

Parameters

distanceFunctionOfClusterMeans  FuncTDataSum, TDataSum, Double
Function to calculate the Euclidean distance between two cluster centroids.

Return Value

Double
The Davies-Bouldin-Index using q=1 (p=2 if distanceFunctionOfClusterMeans returns the Euclidean distance between the cluster centroids).
