A robust principal component analysis
Copyright policy )A robust principal component analysis
L'auteur propose une analyse en composantes principales robuste. La méthode, fondée sur des estimateurs de dispersion robustes, est intéressante; des propriétés asymptotiques sont étudiées sous certaines conditions. Malheureusement, il ne semble pas très aisé, a priori, d'étendre ce travail à d'autres distributions que les bivariées.
