The techno-typological characterization of the lithic industries from trenches H, Z, and N (18 m²) from the Cardina-Salto do Boi archaeological site, in the Côa River valley, combined with the study of the lithic resource management, made it possible to identify three Middle Palaeolithic occupations, dating from (1) ca. 155 ka BP to ca. 80 ka BP, (2) ca. 80 ka BP to 51 ka BP, and (3) 51 ka BP to 39 ka BP. It al...
Global models have been developed to tackle the challenge of forecasting sets of series that are related or share similarities, but they have not been developed for heterogeneous datasets. Various methods of partitioning by relatedness have been introduced to enhance the similarities of sets, resulting in improved forecasting accuracy but often at the cost of a reduced sample size, which could be harmful. To sh...
