[L'estimateur des moindres carrés conditionnels dans les modèles PGARCH et PARMA–PGARCH]
Dans cette Note, on étudie l'estimateur des moindres carrés conditionnels (CLS) dans les modèles GARCH périodiques (PGARCH) dont le carré centré des innovations est une différence de martingale. Cette approche est étendue aux modèles PARMA–PGARCH. La consistance forte et la normalité asymptotique ont été établies.
In this Note, a conditional least squares (CLS) estimates for periodic GARCH (PGARCH) models with martingale difference centered squared innovations is developed. The approach is extended to the PARMA–PGARCH models. We establish the strong consistency and the asymptotic normality for our estimate.
