Fourier Zivot-Andrews enhedsrodstest

Fourier Zivot-Andrews-testen udvider den klassiske Zivot-Andrews (1992) enhedsrodstest ved at erstatte skarpe, enkelte strukturelle break-dummier med en lavfrekvent Fourier-approksimation, hvilket tillader testen at håndtere glidende, gradvise og multiple ukendte breaks i niveauet eller trenden af en tidsserie.
