Les analyses multitableaux en ecologie factorielle. : De la typologie d'etat a la typologie de fonctionnement par l'analyse triadique

Abstract : Triadic analysis is weil adapted to the statistical study of multivariate surveys that are collected more than once. Triadic analysis is a particular case of the so-called "multitable analyses", and therefore benefits from the descriptive power of the underlying theoretical tools of these meth.ods. The interstructure proposes an ordination of the sampling dates anri an overall typology of spatial processes. The compromise expresses the structures common to each date, from bath the viewpoints of variables and sampling sites. The intrastructure offers a detailed description of deviations from the common madel of the compromise for each date. The method proposed here leads to many generalizations concerning this kind of analysis. We present a simple computational procedure, using only principal components analysis
