Statistical proposals for a formal classification of Chalcolithic stone masonry passage graves with circular chamber in the Southeast of the Iberian Peninsula Calvín Velasco, María Eugenia Cámara Serrano, Juan Antonio Esquivel Sánchez, Francisco Javier Chalcolithic period Southeast of the Iberian Peninsula Megaliths Stone masonry grave Flat roof False dome Statistics Funding This study forms part of the research project ‘Producción artesanal y división del trabajo en el Calcolítico del Sudeste de la Península Ibérica: un análisis a partir del registro arqueológico de Los Millares (PARTESI)’ financed by the Agencia Estatal de Investigación del Ministerio de Ciencia e Innovación (PID2020-117437 GB-I00/ AEI/ https://doi. org/10.13039/501100011033). This study offers a classification of 106 megalithic stone masonry passage graves forming part of the Los Millares archaeological complex characterised by circular chambers. The study has employed a statistical method implementing the OneR, JRip and Part classification algorithms as well as multivariate analyses. The research yielded four groups: large tombs capped with flat roofs, small tombs covered by false domes, and two types of medium-large tombs capped either by flat or false-domes that can be distinguished according to the angles of their chambers walls and the presence of construction reinforcements, including the number of stone retainer rings walls serving to brace the thrust. 2023-07-21T10:03:10Z 2023-07-21T10:03:10Z 2023-07-10 journal article M.E.
