Phillips-Ouliaris residualbaserede kointegrationstest

Phillips-Ouliaris-testen, introduceret af Phillips og Ouliaris i deres Econometrica-artikel fra 1990, er en residualbaseret nonparametrisk procedure til at teste nulhypotesen om ingen kointegration blandt et sæt integrerede I(1) tidsserier. Den korrigerer OLS-residualer fra en kointegrationsregression for seriel korrelation og endogenitet ved hjælp af kernelbaserede langsigtede variansestimatorer, hvilket giver to statistikker – Z_alpha (variansforhold) og Z_t (normaliseret koefficient) – hvis asymptotiske fordelinger er tabuleret specifikt for systemer med multiple stokastiske regressorvariabler.
