Clustering Library (ClusteringLib)


getVariance
to calculate variance of clusters



FUNCTIONS

double - getVariance(int[][] data, int[] clusters)
double - getVariance(double[][] data, int[] clusters)




EXAMPLES

Example	VectorLib vlib=new VectorLib(); ClusteringLib clib=new ClusteringLib(); int[][] data={{20, 30}, {30, 20}, {30, 30}, {70, 70}, {80, 80}}; int[] clusters=clib.Clustering("kmeans", data, 2); double[] V=clib.getVariance(data, clusters); vlib.view("Vw", V[0]); vlib.view("Vb", V[1]);
Output	Vw = 77.77777777777777 Vb = 5840.277777777778
