UNIWIN - R\u00e9gression Typologique<\/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]La r\u00e9gression lin\u00e9aire typologique (RTYPO) est une technique statistique qui s’attaque \u00e0 une limitation fondamentale de la r\u00e9gression lin\u00e9aire conventionnelle : l’incapacit\u00e9 \u00e0 saisir des relations complexes au sein d’un ensemble de donn\u00e9es contenant des sous-groupes distincts.<\/p>\n

RTYPO y parvient en partitionnant l’ensemble de donn\u00e9es en plusieurs sous-ensembles, chacun dot\u00e9 de sa propre fonction de r\u00e9gression lin\u00e9aire entre variables ind\u00e9pendantes et d\u00e9pendantes.<\/p>\n

Une description courante, et souvent plus technique, de ce probl\u00e8me consiste \u00e0 partitionner un ensemble de donn\u00e9es h\u00e9t\u00e9rog\u00e8ne en sous-groupes d’observations homog\u00e8nes plus petits, tout en ajustant simultan\u00e9ment des mod\u00e8les de r\u00e9gression lin\u00e9aire adapt\u00e9s \u00e0 chaque sous-groupe.<\/p>\n

RTYPO est une extension naturelle de la formulation conventionnelle de la r\u00e9gression lin\u00e9aire multivari\u00e9e \u00e0 la mod\u00e9lisation de donn\u00e9es contenant des structures de sous-groupes inconnues ou \u00e0 des probl\u00e8mes de r\u00e9gression non lin\u00e9aire se pr\u00eatant \u00e0 une approximation lin\u00e9aire par morceaux.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=\u00a0\u00bb6665″ img_size=\u00a0\u00bblarge\u00a0\u00bb alignment=\u00a0\u00bbcenter\u00a0\u00bb][vc_empty_space height=\u00a0\u00bb5px\u00a0\u00bb][vc_column_text]<\/p>\n
