Modèle de durée pour données multivoie

Abstract : In this paper, we present a multiway extension of Cox proportional hazards model (Multiway Cox). Multi-way data refers to the case where several modalities of the same variable have been collected for each individual. The approach consists in imposing a tensor-like structure to the weight coefficients echoing the structure of the multi-way data set. This approach reduces the number of coefficients to estimate and limits overfitting issues. The proposed procedure is evaluated and validated on simulated data.
