KPSS-testen for strukturelle brud

KPSS-testen for strukturelle brud udvider standard Kwiatkowski-Phillips-Schmidt-Shin (KPSS) stationaritetstesten til at tillade et eller flere kendte eller ukendte strukturelle brud i niveauet eller trenden af en tidsserie. Under nulhypotesen er serien stationær omkring en brudt deterministisk komponent, hvilket gør det muligt for forskere at skelne ægte enhedsrodadfærd fra tilsyneladende ikke-stationaritet forårsaget af regimeskift.
