This program performs clustering on two-dimensional points using agglomerative methods.

Linkage Criteria:

• Single linkage (SL)
• Complete linkage (CL)
• Unweighted pair group method with arithmetic mean (UPGMA)
• Unweighted pair group method with centroid average (UPGMC)
• Ward's method (WM)

Determining the Number of Clusters:

• Silhouette method (SM)
• e-2 hypothesis (E2H)
