Table 1 CPCC results for different versions of AGNES algorithm

AGNES algorithm	Cophenetic correlation coefficient (CPCC)
AGNES algorithm	DTW	TDM	Euclidean
Single	0.7378	0.7101	0.6650
Complete	0.5690	0.5124	0.5266
Average	0.7949	0.7692	0.7411
Ward	0.6003	0.6306	0.6199
Weighted	0.7186	0.6916	0.6886
Median	0.6602	0.6284	0.5627
Centroid	0.7630	0.7243	0.6872

The number in italics shows the highest CPCC value for DTW, TDM and Euclidean distances under average version. Hence, Average AGNES algorithm using DTW has been selected for clustering the data because it has highest CPCC value
