Abstract
The transfer of advances in chemometrics into archaeometric research opens up a wide range of new application possibilities in this rapidly developing field. Neutron activation analysis (NAA) of ceramic samples from the Banda Traditional Area (west‐central Ghana) combined with chemometrics allowed us to establish a link between current and ancient systems of ceramics production in the historic settlements of Kuulo Kataa and Makala Kataa. Principal component analysis (PCA) and the soft independent modelling of class analogy (SIMCA) method were applied to the Das Dores Cruz data set in order to unequivocally determine the geographical origin of the diverse archaeological samples. After global autoscaling pretreatment, PCA analysis showed a clear difference between samples from different locations. The classification models obtained by SIMCA showed a classification ability of 100% and a prediction ability of 97.7%, with a mean sensitivity of 84% and a specificity of 100% for the three categories. The application of SIMCA showed that some NAA variables (elements) were more important than others in terms of geographical classification. With the class models that we obtained, we were able to determine the origin of the ancient remains. SIMCA has proved to be a powerful technique for the class modelling of archaeological data.

Neutron activation analysis (NAA) of ceramic samples from the Banda Traditional Area (west‐central Ghana) combined with chemometrics allowed us to establish a link between current and ancient systems of ceramics production in the historic settlements of Kuulo Kataa and Makala Kataa. Principal component analysis (PCA) and the soft independent modelling of class analogy (SIMCA) method were applied to the Das Dores Cruz data set in order to unequivocally determine the geographical origin of the diverse archaeological samples. After global autoscaling pretreatment, PCA analysis showed a clear difference between samples from different locations. The classification models obtained by SIMCA showed a classification ability of 100% and a prediction ability of 97.7%, with a mean sensitivity of 84% and a specificity of 100% for the three categories. The application of SIMCA showed that some NAA variables (elements) were more important than others in terms of geographical classification. With the class models that we obtained, we were able to determine the origin of the ancient remains. SIMCA has proved to be a powerful technique for the class modelling of archaeological data.</abstract><subject lang="en"><genre>keywords</genre><topic>BANDA AREA (GHANA)</topic><topic>NEUTRON ACTIVATION ANALYSIS</topic><topic>CERAMICS</topic><topic>CHEMOMETRICS</topic><topic>PRINCIPAL COMPONENT ANALYSIS (PCA)</topic><topic>SOFT INDEPENDENT MODELLING OF CLASS ANALOGY (SIMCA)</topic><topic>MULTIVARIATE ANALYSIS</topic></subject><relatedItem type="host"><titleInfo><title>Archaeometry</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">0003-813X</identifier><identifier type="eISSN">1475-4754</identifier><identifier type="DOI">10.1111/(ISSN)1475-4754</identifier><identifier type="PublisherID">ARCM</identifier><part><date>2012</date><detail type="volume"><caption>vol.</caption><number>54</number></detail><detail type="issue"><caption>no.</caption><number>1</number></detail><extent unit="pages"><start>101</start><end>113</end><total>13</total></extent></part></relatedItem><identifier type="istex">D1A953FDCCF635D2A27863985C6B66D2C1C32266</identifier><identifier type="DOI">10.1111/j.1475-4754.2011.00601.x</identifier><identifier type="ArticleID">ARCM601</identifier><accessCondition type="use and reproduction" contentType="copyright">© University of Oxford, 2011</accessCondition><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
