In statistics, an augmented Dickey–Fuller test (ADF) tests the null hypothesis that a unit root is present in a time series sample. The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity. It is an augmented version of the Dickey–Fuller test for a larger and more complicated set of time series models. The augmented Dickey–Fuller (ADF) statistic, used in the test, is a negative number. The more n… Webb24 sep. 2024 · How to run and interpret the fundamental tests in GAUSS including the Augmented Dickey-Fuller (ADF) and Phillips-Perron unit root tests and the KPSS stationarity test.

WebbThe Phillips-Perron test is similar to the ADF except that the regression run does not include lagged values of the first differences. Instead, the PP test fixed the t-statistic … WebbThe most popular of these tests are the Dickey-Fuller (ADF) test and the Phillips-Perron (PP) test. The ADF and PP tests differ mainly in how they treat serial correlation in the test regressions. 1. ADF tests use a parametric autoregressive struc-ture to capture serial correlation φ∗(L)ut = εt φ∗(L)=1−φ∗ 1L−···−φ∗kLk 2.
Webbaugmented Dickey–Fuller test’s regression includes lags of the first differences of y t. The Phillips–Perron test involves fitting(1), and the results are used to calculate the test statistics.
