Web23 de fev. de 2024 · An Example of Hierarchical Clustering. Hierarchical clustering is separating data into groups based on some measure of similarity, finding a way to measure how they’re alike and different, and further narrowing down the data. Let's consider that we have a set of cars and we want to group similar ones together. WebNow we got the two required information and we can put them together into a single matrix. Cophenetic Correlation Coefficient is simply correlation coefficient between distance matrix and Cophenetic matrix =Correl (Dist, CP) = 86.399%. As the value of the Cophenetic Correlation Coefficient is quite close to 100%, we can say that the clustering ...
