Robust Engle-Granger Kointegrationstest

Den robuste Engle-Granger kointegrationstest tilpasser den klassiske to-trins Engle-Granger procedure til at modstå outliers, fejlfordelinger med tunge haler og additiv støj, som kan forvrænge standard residual-baseret kointegrationsinferens alvorligt. Ved at erstatte klassiske OLS- og ADF-trin med robust regression og robust enhedsrodstestning, giver den pålidelige konklusioner om langsigtede ligevægtsrelationer, selv når data indeholder anomale observationer.
