Kipimo cha Uunganishaji wa Johansen na Kielelezo cha Mfumo wa Kurekebisha Makosa
Utaratibu wa Johansen ni mfumo wa uunganishaji wa pande nyingi, ulioanzishwa na Søren Johansen mnamo 1991, unaojaribu uhusiano wa muda mrefu wa usawa miongoni mwa mfululizo kadhaa wa nyakati wa I(1). Unabainisha ni vekta ngapi za uunganishaji huunganisha mfululizo na kisha hujenga Kielelezo cha Mfumo wa Kurekebisha Makosa (VECM) kuelezea mienendo ya muda mfupi karibu na usawa huo.
