Cluster analysis is a versatile and exploratory data analysis technique used to identify natural groupings or clusters within a dataset. It is also known as segmentation analysis or taxonomy analysis and is particularly useful when the groupings within data are not previously known. This technique is exploratory in nature, focusing solely on ...

Planteamiento general. El análisis cluster es un conjunto de técnicas multivariantes utilizadas para clasificar a un conjunto de individuos en grupos homogéneos. Pertenece, al igual que otras tipologías y que el análisis discriminante al conjunto de técnicas que tiene por objetivo la clasificación de los individuos.
Cluster Analysis 1 Clustering Techniques Much of the history of cluster analysis is concerned with developing algorithms that were not too computer intensive, since early computers were not nearly as powerful as they are today. Accordingly, computational shortcuts have traditionally been used in many cluster analysis algorithms.
Cluster Analysis. R offers a wide range of functions for cluster analysis, including hierarchical agglomerative, partitioning, and model-based approaches. Although there is no definitive solution for determining the optimal number of clusters to extract, several approaches are available.
Cluster analysis is a data exploration (mining) tool for dividing a multivariate dataset into “natural” clusters (groups). We use the methods to explore whether previously undefined clusters (groups) exist in the dataset. For instance, a marketing department may wish to use survey results to sort its customers into categories (perhaps those likely to be most receptive to buying a product ...
