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. WebbI have quarterly data from 2009 Q1 to 2024 Q2, and I would like to run an ARIMA forecast model on this data. In order to do that, it is my understanding that I need to first make my data stationary. In order to check for stationarity I am using the Phillips-Perron test (also the ADF and KPSS).
