The two-step algorithm uses the(agglomerative) hierarchical clustering method, because it works well with the auto-cluster method. The algorithm is based on a distance measure that gives the best results if all variables are independent, the continuous variables have a normal distribution, and the categorical variables have a multinomial distribution.

OBS

two-step algorithm: A "two-step algorithm" should not be confused with a "two-stage algorithm." "Two-step" refers to a process involving two sequential actions, while "two-stage" implies a process with distinct levels or phases of operation.

Agglomerative hierachy clustering algorithm. This is the most common type of hierarchical clustering algorithm. It's used to group objects in clusters based on how similar they are to each other. This is a form of bottom-up clustering, where each data point is assigned to its own cluster. Then those clusters get joined together. At each iteration, similar clusters are merged until all of the data points are part of one big root cluster.

Agglomerative clustering is the most frequent class of hierarchical clustering, used to put items in clusters based on similarities. In this approach, each item is first treated as a singleton cluster. Following this, pairs of clusters are merged one by one until all the clusters have been combined into a single large cluster holding all items. The output is a dendrogram, a tree-based presentation of the items...

Le principe du regroupement hiérarchique ascendant ou agglomératif considère, au départ, que chaque individu est un regroupement en soit. Ensuite, à chaque étape, des groupes sont constitués par agrégation des deux individus les plus proches de la partition de l'étape précédente. Le processus de regroupement s'arrête lorsqu'on arrive à former un seul groupe [...] Le dendrogramme issu du regroupement agglomératif est construit de manière ascendante [...]

Monothetic clustering is a divisive clustering method that uses a hierarchical, recursive partitioning of multivariate responses based on binary decision rules that are built from individual response variables... Based on the ideas of classification and regression trees, a monothetic clustering algorithm was implemented... to allow further explorations and modifications.
