Robust Vector Error Correction Model (Robust VECM)

Robust VECM udvider den klassiske Vector Error Correction Model ved at erstatte ordinary least squares (OLS) estimering med procedurer, der er resistente over for outliers — såsom M-estimatorer, S-estimatorer eller least trimmed squares — således at kointegrationsrelationer og kortsigtede justeringsdynamikker estimeres pålideligt, selv når den multivariate tidsserie indeholder outliers, strukturelle brud eller innovationer med tunge haler.
