CORRALES, David  e  RODRIGUEZ, Oldemar. Interstatis: the statis method for interval valued data. Rev. Mat [online]. 2014, vol.21, n.1, pp.73-83. ISSN 1409-2433.

The STATIS method, proposed by L’Hermier des Plantes and Escoufier, is used to analyze multiple data tables in which is very common that each of the tables have information concerning the same set of individuals. The differences and similitudes between said tables are analyzed by means of a structure called the compromise. In this paper we present a new algorithm for applying the STATIS method when the input consists of interval data. This proposal is based onMoore’s interval arithmetic and the Centers Method for Principal Component Analysis with interval data, proposed by Cazes el al. [5]. In addition to presenting the INTERSTATIS method in an algorithmic way, an execution example is shown, alongside the interpretation of its results.
