International audienceIn social sciences or medicine, studies are often based on questionnaires asking participants to express ordered responses several times over a study period. We present a model to perform temporal clustering on such data. The model relies on mixture of matrix-variate normal distributions, accounting for the within and between time-dependence structures simultaneously. A MC-EM algorithm for the model estimation is used. Applications on synthetic and real data are presented.Dans les sciences sociales ou la médecine, les études sont souvent basées sur des questionnaires demandant aux participants d'exprimer des réponses ordonnées à plusieurs reprises au cours d'une période d'étude.
