Abstract

Within the framework of the ANITES methodology, designed for the study of the spatial articulation of the archaeological record, we use a remodelled version of the nearest-neighbour in 3D, that computes the distances between three-dimensional points (x, y, z). In this paper we present some technical questions related to performances for the study of the distribution patterns and for the determination of the spatial category groups. We use a comparison between the results obtained in different data processing (El Cingle Vermell, El Roc del Migdia, Túnel VII and Punta Baja sites) to evaluate the relationships and incidence of the variables involved (values of the coefficient R, critical distance, number of effective and number of category groups). This technical evaluation shows that the test of the nearest-neighbour in 3D works for our expectation and is very useful when inserted in the framework of the ANITES methodology.
