ADF test jediničnog korena sa strukturnim prelomom

ADF test jediničnog korena sa strukturnim prelomom proširuje standardni prošireni Dickey-Fullerov test (ADF) kako bi se omogućilo jedno ili više diskretnih pomeranja u nivou ili trendu vremenske serije. Budući da ignorisanje strukturnog preloma naduvava prividnu perzistenciju serije, ovaj test sprečava lažno prihvatanje nulte hipoteze o jediničnom korenu kada je serija zapravo stacionarna oko pomerajuće sredine ili trenda.
