Webb21 juli 2024 · Whether the stationarity in the null hypothesis is around a mean or a trend is determined by setting β=0 (in which case x is stationary around the mean r₀) or β≠0, respectively. The KPSS test is often used to complement Dickey-Fuller-type tests. I will touch on how to interpret such combined results in a future post.

Webb14 dec. 2024 · Phillips and Perron (1988) propose an alternative (nonparametric) method of controlling for serial correlation when testing for a unit root. The PP method estimates the non-augmented DF test equation (42.4) , and modifies the -ratio of the coefficient so that serial correlation does not affect the asymptotic distribution of the test statistic. WebbPhillips dan Perron[11] mengusulkan metode alternatif nonparametrik untuk menguji serial korelasi dengan akar unit. Untuk menyelesaikan masalah parameter gangguan, digunakan estimator konstan untuk 2 σu dan σ2 untuk melakukan transformasi statistik ( −1) ∧ T α dan ∧ α t dengan cara menghilangkan pengaruh parameter gangguan.
