[Test d'un modèle non paramétrique pour des séries chronologiques lorsque les vecteurs aléatoires sont non stationnaires et absolument réguliers]
Dans cette note, nous étudions quelques méthodes générales pour tester un modèle paramétrique associé à une série chronologique markovienne à valeurs réelles lorsque les vecteurs aléatoires sont non stationnaires et absolument réguliers. Notre idée est d'utiliser un processus empirique marqué basé sur les résidus qui converge en loi vers un processus gaussien.
In this Note, we study some general methods for testing the goodness-of-fit of a parametric model for a real-valued Markovian time series under nonstationarity and absolute regularity. For that, we define a marked empirical process based on residuals, which converges in distribution to a Gaussian process with respect to the Skorohod topology. This method was first introduced by Koul and Stute [1], and then widely developed by Ngatchou-Wandji [2,3] under more general conditions. Applications to general AR-ARCH models are given.
