Kipimo cha Mizizi ya Unit ya Fourier Zivot-Andrews

Kipimo cha Fourier Zivot-Andrews huongeza kipimo cha kawaida cha mizizi ya unit cha Zivot-Andrews (1992) kwa kubadilisha vipindi vikali, vya mara moja vya mabadiliko ya kimuundo na mlinganyo wa masafa ya chini wa Fourier, kuruhusu kipimo kushughulikia mabadiliko laini, yanayoendelea, na mengi yasiyojulikana katika kiwango au mwelekeo wa mfululizo.
