Hierarchical Clustering

Agglomerative Hierarchical Clustering

Performing AHCA

To perform AHCA, select Analysis->Multivariate Analysis->Hierarchical Clustering from the Vespucci main window. Here you may select a linkage criterion and a distance metric. The Ward linkage criterion can only be used with the squared Euclidean distance metric.

"Under the Hood"

Vespucci uses a bespoke AHCA implementation, located in agglomerativeclustering.cpp
