discriminant factor analysis or discriminant analysis is a descriptive technique factor which is to convey to Using a set of variables of individuals belonging to groups (classes) predefined. Which is primarily a descriptive method. Nevertheless, by definition, it has connections with very important discriminant analysis or Bayesian predictive discriminant analysis, well-known supervised learning and pattern recognition.
discriminant analysis is descriptive factorial approaches. It is shown quite easily that it is a particular variation of the canonical analysis and principal component analysis.
This new show is the support that I will use now to describe the method to my students. It can be decomposed into three parts: presentation of the method and main theoretical elements; reading résultats, notamment l'interprétation des axes factoriels ; mise en œuvre dans les logiciels tels que Tanagra (Canonical Discriminant Analysis), R (lda) et SAS (candisc).
Ce support doit beaucoup aux excellents ouvrages de Tenenhaus (2007) et Saporta (2006) indiqués dans la bibliographie.
