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).

Webb30 juli 2024 · First, the stationarity of all variables is tested by using Phillips and Perron (1988) and Dickey and Fuller (1979) unit root tests. Stationary checking is not necessary for the ARDL method. We may apply the ARDL model when all variables are merely stationary at I(0), or I(1) or a mixture of I(1) and I(0). WebbThe null hypothesis of the Phillips-Perron (PP) test is that there is a unit root, with the alternative that there is no unit root. If the pvalue is above a critical size, then the null cannot be rejected that there and the series appears to be a unit root. citrix receiver swissport.com
