MA-model med strukturelle brud

En Moving Average (MA) tidsseriemodel udvidet til at rumme et eller flere strukturelle brud — pludselige skift i middelværdien, variansen eller MA-koefficienterne, der forekommer på kendte eller ukendte bruddatoer. Ignorering af strukturelle brud i en MA-proces oppuster prognosefejl og forvrænger inferens om fejl-dynamikken.
