Hierarchical clustering on principal components (HCPC) is a hybrid approach that combines the strengths of principal component analysis (PCA) and hierarchical clustering. PCA first reduces the dimensionality of the dataset by summarizing correlated variables into a smaller set of uncorrelated components that retain most of the original variance. Then, hierarchical clustering is performed on these principal components instead of the raw variables, which enhances the separation of clusters and reduces noise caused by variable correlations. This method is particularly useful for visualizing and identifying meaningful groupings in complex multivariate datasets, as it simplifies interpretation while preserving the main structure of the data. The results presented in the HCPC tab are entirely distinct from those in the Analysis Results tab, as they are derived from clustering performed on the principal components obtained through PCA, providing a more refined and dimensionally reduced perspective of the dataset.
