Kipimo cha Uthabiti cha Ukozi wa Johansen

Kipimo cha Uthabiti cha Ukozi wa Johansen kinapanua mfumo wa zamani wa uwezekano wa kuamua cheo cha ukozi wa mfumo wa multivariate I(1) kwa mujibu wa Johansen (1988, 1991) hadi katika mazingira ambapo dhana za kawaida za Gaussian zinashindwa — hasa wakati data ina mambo ya nje, uvumbuzi wenye mikia minene, au heteroskedasticity ya masharti. Marekebisho thabiti hurekebisha mabaki, huwapa uzito upya uchunguzi, au huhesabu kwa njia ya bootstrap maadili muhimu ili uhitimisho wa cheo ubaki kuwa halali chini ya ukiukaji huu.
