Robust ARIMA-model

Robust ARIMA udvider det klassiske ARIMA-rammeværk til at detektere og korrigere indflydelsen af outliers og strukturelle brud under estimering. Ved at identificere anomale observationer og re-estimere modelparametre producerer den koefficientestimater og prognoser, der er langt mindre forvrængede af isolerede chok eller datafejl end standard ARIMA.
