In this paper we examine the problem of compositional data from a different starting
point. Chemical compositional data, as used in provenance studies on archaeological
materials, will be approached from the measurement theory. The results will show, in a
very intuitive way that chemical data can only be treated by using the approach
developed for compositional data. It will be shown that compositional data analysis is a
particular case in projective geometry, when the projective coordinates are in the
positive orthant, and they have the properties of logarithmic interval metrics. Moreover,
it will be shown that this approach can be extended to a very large number of
applications, including shape analysis. This will be exemplified with a case study in
architecture of Early Christian churches dated back to the 5th-7th centuries AD Geologische Vereinigung; Institut d’EstadÃstica de Catalunya; International Association for Mathematical Geology; Cà tedra LluÃs Santaló d’Aplicacions de la Matemà tica; Generalitat de Catalunya, Departament d’Innovació, Universitats i Recerca; Ministerio de Educación y Ciencia; Ingenio 2010. |
