HierarchicalLinkage

HierarchicalLinkage = "single" | "average" | "complete" | "ward"

Defined in: hierarchical-cluster.ts:14

Linkage criterion for computing inter-cluster distances.

  • "single" — minimum pairwise distance. Prone to chaining.
  • "average" — mean pairwise distance (UPGMA). Balanced; default.
  • "complete" — maximum pairwise distance. Compact clusters; eliminates chaining.
  • "ward" — minimises the increase in total within-cluster variance (Ward’s minimum-variance criterion). The threshold is in Ward-distance units (√ΔTWCSS), which differ from the raw distance units of getDistance.
