Ujian Punca Unit ADF Bayesian

Ujian punca unit Bayesian Augmented Dickey-Fuller (BADF) membingkai semula ujian ADF klasik dalam rangka kerja Bayesian. Berbanding mengira nilai-p frekuentis, ia mengukur bukti menyokong atau menentang punca unit dengan membandingkan kebarangkalian posterior atau faktor Bayes di bawah hipotesis sifar (punca unit) dan hipotesis alternatif (kesetabilan), menggabungkan kepercayaan awal tentang parameter autoregresif.
