Abstract (English): We consider a pure-jump stable Cox-Ingersoll-Ross (α-stable CIR) process driven by a non-symmetric stable Lévy process with jump activity α ∈ (1,2), for which estimators of the drift, scaling and jump activity parameters from high-frequency observations of the process on a fixed time period have been proposed in previous work [BC23]. We first present a numerical scheme to simulate this process. Next, we describe the challenge presented by the non-symmetric stable Lévy process when computing its density and its derivatives. We finally implement the estimators and carry out simulations to show good estimation accuracy. [ABSTRACT FROM AUTHOR]
Abstract (French): Nous considérons un processus de Cox-Ingersoll-Ross stable (α-stable CIR) dirigé par un processus de Lévy stable non symétrique d'indice d'activité des sauts α ∈ (1,2), pour lequel des estimateurs des paramètres de tendance, d'échelle et d'activité des sauts à partir d'observations haute fréquence du processus sur une période de temps fixe ont été proposés dans des travaux antérieurs [BC23]. Nous présentons d'abord un schéma numérique pour simuler ce processus. Ensuite, nous décrivons la difficulté que représente le processus de Lévy stable non symétrique lors du calcul de sa densité et de ses dérivées. Enfin, nous implémentons les estimateurs et effectuons des simulations de Monte-Carlo pour montrer la bonne précision de l'estimation. [ABSTRACT FROM AUTHOR]
