Model strukturnog preloma EGARCH

Model strukturnog preloma EGARCH kombinuje Nelsonov Eksponencijalni GARCH okvir sa eksplicitnim dopuštanjem jednog ili više strukturnih preloma u procesu volatilnosti. Dozvoljavajući da se presecni član i parametri upornosti jednačine log-varijanse promene na detektovanim datumima preloma, model izbegava lažnu dugotrajnu memoriju i uvećanu upornost sa kojima se standardni EGARCH suočava kada podaci sadrže promene režima.
