Outcomes for two … WebIn agglomerative hierarchical clustering, the analysis begins with each observation as a separate cluster. The analysis goes through several rounds, joining similar observations (as measured by the variables in the data) into clusters one step at a time, with each step using a more generous definition of "similar."
Web4.1.4.1 Silhouette. One way to determine the quality of the clustering is to measure the expected self-similar nature of the points in a set of clusters. The silhouette value does just that and it is a measure of how similar a data point is to its own cluster compared to other clusters (Rousseeuw 1987).
