type LinkageMethod

Single	0	The distance between two clusters is the distance between their closest neighboring points.
Complete	1	The distance between two clusters is the distance between their two furthest member points.
Average	2	Also called unweighted pair-group method using averages (UPGMA). The distance between two clusters is the average distance between all inter-cluster pairs.
Ward	3	The cluster to be merged is the one which will produce the least increase in the sum of squared Euclidean distances from each case in a cluster to the mean of all variables.
Median	4	Also called unweighted pair-group method using centroid averages (UPGMC). The cluster to be merged is the one with the smallest sum of Euclidean distances between cluster means (centroids) for all variables.
McQuitty	5	The distance between a cluster and a newly merged cluster is the mean of the distance between the cluster and each of the two component clusters.
Centroid	6	The distance between two clusters is the distance between the centroids or the means of the clusters.
