Choice of trimming proportion and number of clusters in robust clustering based on trimming
Luis Angel García-Escudero, Christian Hennig, Agustín Mayo-Iscar +2
So-called "classification trimmed likelihood curves" have been proposed as a useful heuristic tool to determine the number of clusters and trimming proportion in trimming-based rob…
