Statistical proposals for a formal classification of Chalcolithic stone masonry passage graves with circular chamber in the Southeast of the Iberian Peninsula

A statistical analysis of 106 megalithic passage graves at the Los Millares archaeological complex reveals four distinct groups based on structural characteristics. These include large tombs with flat roofs, small tombs covered by false domes, and two medium-large types distinguished by chamber wall angles and construction reinforcements such as stone retainer rings. The study employed OneR, JRip, and Part classification algorithms alongside multivariate analyses to formalize this classification, offering new insights into Chalcolithic stone masonry techniques in the Southeast Iberian Peninsula.
