UNIWIN - Classification Ascendante Hi\u00e9rarchique<\/h2><\/div><\/div>[\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

La m\u00e9thode de Classification Ascendante Hi\u00e9rarchique (CAH) permet de construire une typologie (ou partition) d’un ensemble d’individus en classes telles que les individus appartenant \u00e0 une m\u00eame classe sont proches alors que les individus appartenant \u00e0 des classes diff\u00e9rentes sont \u00e9loign\u00e9s.<\/p>\n

La m\u00e9thode utilis\u00e9e est celle de Ward, m\u00e9thode dite des voisins r\u00e9ciproques. C’est une m\u00e9thode ascendante partant d’un nombre de classes \u00e9gal au nombre des individus et regroupant \u00e0 chaque it\u00e9ration un (ou plusieurs) individus ou classes en fonction de la diminution de l’inertie inter-classes.<\/p>\n

L’algorithme s’applique \u00e0 des donn\u00e9es quantitatives individus x variables (avec standardisation ou non), \u00e0 un tableau de contingence ou \u00e0 un tableau de variables qualitatives. Dans le cas d’un tableau de contingence, la classification peut se faire suivant les lignes ou les colonnes.<\/p>\n

Un tableau r\u00e9sum\u00e9 de la classification et le trac\u00e9 de l’arbre de classification (avec zoom et troncature) et de nuages codifi\u00e9s sont propos\u00e9s ainsi que des outils d’analyse de la partition et des noeuds.<\/p>\n
