We propose a statistical approach to comparing the DBSCAN and HDBSCAN clus-tering algorithms. The approach examines transitions in object status (core, border, or noise) andthe association between clustering results. The neighborhood radius ε for DBSCAN is selectedsubject to a constraint defined by the proportion of objects labeled as noise by HDBSCAN. Theresulting assignments are analyzed using contingency tables, Pearson’s χ 2 statistic, CramГ©r’s V ,and Tschuprow’s T. A computational experiment is conducted on data with clusters of differingdensities. The two algorithms identify nearly identical numbers of noise objects. CramГ©r’s Vincreases with the number of nearest neighbors k, whereas Tschuprow’s T shows an overall increasebut is not monotonic. The results support the use of HDBSCAN-derived information for calibratingDBSCAN and for a statistical comparison of density-based clustering results.
