The Phillips Curve Economic Theory Explained
WebbAugmented Dickey–Fuller and Phillips–Perron tests have been shown to have relatively low power to reject their null hypothesis: that the series is non-stationary (I(1)) rather than stationary (I(0)). In particular, any sort of structural break in the series is likely to cause a failure to reject, even if the series is WebbThere are two different approaches: stationarity tests such as the KPSS test that consider as null hypothesis H0 that the series is stationary, and unit root tests, such as the Dickey-Fuller test and its augmented version, the augmented Dickey-Fuller test (ADF), or the Phillips-Perron test (PP), for which the null hypothesis is on the contrary that the series … raymond moving equipment
