Modeli wa Kurekebisha Hitilafu wa Kipeo Imara (Robust VECM)

Robust VECM inapanua Model ya Kurekebisha Hitilafu ya Kipeo (VECM) ya kawaida kwa kubadilisha makadirio ya mlinganyo wa mabaki madogo zaidi (ordinary least squares) na taratibu zinazostahimili mkengeuko — kama vile vipimo-M (M-estimators), vipimo-S (S-estimators), au mraba zilizopunguzwa zaidi (least trimmed squares) — ili mahusiano ya ushirikiano wa muda mrefu (cointegration) na mienendo ya marekebisho ya muda mfupi yakadiriwe kwa uhakika hata pale data ya vipindi vingi vya nyakati inapokuwa na mkengeuko, mabadiliko ya kimuundo, au uvumbuzi wenye miisho minene.
