Artigo IPEN-doc 22506 Study of exchange networks between two Amazon archaeological sites by INAA2015 - HAZENFRATZ, R.; MUNITA, C.S.; GLASCOCK, M.D.; MONGOLO, G.Z.; NEVES, E.G.Artigo IPEN-doc 15739 Testing multivariate normality of elemental concentration data obtained by INAA2010 - HAZENFRATZ, ROBERTO; MUNITA, CASIMIRO S.; NEVES, EDUARDO G.The ceramic provenience studies are important in Archaeology due to its potential to infer the materials source used in the ceramic manufacture, which is an indicative of the socio-cultural interactions among ancient societies. A study of provenience was carried out using the elemental concentrations (Na, Lu, U, Yb, La, Th, Cr, Cs, Sc, Fe, Eu, Ce, Hf, Tb) of 50 ceramic fragment samples obtained by Instrumental Neutron Activation Analysis (INAA), from the Lago Grande archaeological site, in the central Amazon, Brazil. The preliminary multivariate statistical analysis of the ceramics elemental concentration suggested the existence of two distinct groups of different elemental composition. In archaeometric studies, the elemental concentrations are usually logarithmically transformed, based on the assumption that the trace elements have a natural lognormal distribution in nature. The normality is often desirable in multivariate analysis. In this paper, the lognormal distribution of concentrations was tested for multivariate normality, in order to validate the application of some multivariate statistical techniques.Artigo IPEN-doc 16713 Comparison of INAA elemental composition data betwen Lago Grande and Oswaldo Archaeological Sites in the Central Amazon: A first perspective2011 - HAZENFRATZ, ROBERTO; MONGELO, GUILHERME; MUNITA, CASIMIRO S.; NEVES, EDUARDO G.Artigo IPEN-doc 17148 Variable selection using procrustes analysis for an INAA compositional study in the Central Amazon2011 - HAZENFRATZ, ROBERTO; OLIVEIRA, PAULO M.S.; MUNITA, CASIMIRO S.; NEVES, EDUARDO G.Artigo IPEN-doc 15217 Preliminary characterization of ceramics from the Lago Grande archaeological site in the central amazon by INAA2009 - HAZENFRATZ, ROBERTO; MUNITA, CASIMIRO S.; NEVES, EDUARDO G.; OLIVEIRA, PAULO M.S.; TOYOTA, ROSIMEIRI G.Artigo IPEN-doc 17736 Comparison of INAA elemental composition data between Lago Grande and Osvaldo archaeological sites in the central Amazon: a first perspective2012 - HAZENFRATZ, ROBERTO; MONGELO, GUILHERME; MUNITA, CASIMIRO S.; NEVES, EDUARDO G.
