Kointegrationstest (Johansen / Engle-Granger)

Kointegrationstesten undersøger, hvorvidt ikke-stationære tidsserier, der hver indeholder en enhedsrod, deler et stabilt langsigtet ligevægtsforhold. Engle og Granger (1987) introducerede den enkeltlignings residualtilgang, og Johansen (1988) systembaserede rangtilgang.
