Kipimo cha Mizizi ya Muundo Zivot-Andrews

Kipimo cha Zivot-Andrews ni kipimo cha mizizi ya muundo kinachoamua kiwango cha kuvunjika kutoka kwa data badala ya kukilazimisha kutoka nje. Kinapima mizizi ya kitengo dhidi ya mbadala wa utulivu karibu na kuvunjika moja kwa moja kwa muundo — kwa wastani, mwelekeo, au zote mbili — kikichagua tarehe ya kuvunjika ambayo inatoa ushahidi wenye nguvu zaidi dhidi ya dhana sifuri.
