eLMWardFunction0 Ward's method uses an analysis of variance approach to evaluate the distances between clusters. The smaller the increase in the total within-group sum of squares as a result of joining two clusters, the "closer" they are. The within-group sum of squares of a cluster is defined as the sum of the squares of the distance between all objects in the cluster and the centroid of the cluster. Ward's method tends to produce compact groups of well-distributed size.
eLMWeightedAverageFunction1 This method is sometimes referred to as "weighted pair-group method using arithmetic averages," and abbreviated WPGMA.
eLMSingleFunction2 Adopting a friends-of-friends clustering strategy closely related to the minimal spanning tree, the single linkage method tends to result in long "chains" of clusters.
eLMMedianFunction3 This is sometimes referred to as "weighted pair-group method using the centroid average," and abbreviated WPGMC.
eLMCompleteFunction4 The complete linkage method tends to work well in cases where objects form naturally distinct "clumps."
eLMCentroidFunction5 The centroid of a cluster is the average point in the multidimensional space. The centroid method is sometimes referred to as "unweighted pair-group method using the centroid average," and abbreviated UPGMC.
