In this artticle, we consider the order estimation of autoregressive modelswith incomplete data using expectation maximization(EM) algorithm based information criteria.The criteria take the form of a penalization of the conditionnal expectation of the log-likelihood. The ealuation of the penalization term generally involves numerical differenciation and matrix inversion. We introduce a simplification of the penalization term for autoregressive model selection and we propose a penalty factor based on a resampling procedure in the criteria formula. The simulation results show the improvement yielded by the proposed method when compares to the classical information criteria for model selection with incomplete data. |
