C. Pizarro et al., Usefulness of Chemometrics to Classify Pottery Sherds Belonging to the Southeast of the United States Usefulness of Chemometrics to Classify Pottery Sherds Belonging to the Southeast of the United States

The compositional information of an Instrumental Neutron Activation Analysis (INAA) of pottery sherds from the Southeast of United States belonging to the Steponaitis set in MURR database was combined with Chemometric techniques to create a geographical classification. This study allows not only to confirming previous conclusions (Steponaitis et al.1996) for the classification in four geographical areas but also for subdividing the samples into finer units with good classification and prediction results validated by leave-one-out cross validation
