Ward's procedure is a variance method that minimizes the sum of squared Euclidean distance to the cluster means. This is done by considering the increase in the variance of each cluster when merged with another cluster, and choosing the merge that leads to the smallest increase in variance. This makes it a popular choice for hierarchical clustering. Optimizing partitioning methods, sequential threshold methods, and parallel threshold methods are all different types of clustering methods, but they do not specifically use the squared Euclidean distance and are not variance-based.
