VI- Conclusion
Ce rapport de recherche a permis de comparer les
résultats de prévision du modèle HAR(3)-RV de Corsi (2009)
appliqué à des séries de hautes fréquences du CHK
stock regroupées en fréquence de 5 minutes et en fréquence
optimale selon Bandi et Russell (2007) qui est de 9 minutes dans le cadre de ce
travail. L'analyse descriptive des deux séries à partir de leur
auto-corrélogramme laisse présager une certaine
stationnarité des séries journalière ce que le test de
Philippes et Perron (PP) confirme. Cependant l'estimation des modèles
complets ne permet pas conclure que certains coefficients du modèle
HAR(3)-RV sont statistiquement différents de zéro. On
procède quand même à des prévisions hors
échantillons pour 40 jours en utilisant le principe de la fenêtre
récursive. La comparaison de la performance des deux séries est
faite sous la base de comparaison de leur HRMSE. Cette étude a donc
permis ( malgré certains anomalies rencontrée au niveau de
certains résultats) de confirmer que la fréquence optimale
proposée par Bandi et Russell (2007) permet d'effectuer une meilleure
prévision que la fréquence de 5 minutes
généralement utilisée.
