INTERSTATIS: The STATIS method for interval valued data

The STATIS method, proposed by L'Hermier des Plantes and Escoufier, is usedto analyze multiple data tables in which is very common that each of the tableshave information concerning the same set of individuals. The differences andsimilitudes between said tables are analyzed by means of a structure called the\emph{compromise}. In this paper we present a new algorithm for applying theSTATIS method when the input consists of interval data. This proposal is basedon Moore's interval arithmetic and the Centers Method for Principal ComponentAnalysis with interval data, proposed by Cazes el al. \cite{cazes1997}. Inaddition to presenting the INTERSTATIS method in an algorithmic way, anexecution example is shown, alongside the interpretation of its results.
