Mfumo Imara wa Kujirejesha (Robust Autoregressive Model)
Mfumo imara wa AR huweka vipimo vya mfuatano wa wakati wa kujirejesha kwa kutumia mbinu za kukadiria — kwa kawaida M-estimators au estimators zenye athari zilizozuiliwa — ambazo hupinga upotoshaji kutoka kwa maadili ya nje (outliers) na usambazaji wa makosa wenye mikia minene. Tofauti na kukadiria kwa AR kwa kutumia OLS, aina imara hupunguza uzito wa uchunguzi uliokithiri ili idadi ndogo ya data zilizochafuka isiweze kutawala mienendo iliyofitiwa.
