Webb9 apr. 2024 · Perron ( 1989) showed that structural change and unit roots are intimately related, and it is important to note that conventional unit root tests (as performed in many of the reviewed studies) are biased toward a false unit root null when the data are trend-stationary with a structural break. 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.
