WebMar 11, 2024 · Hi, im currently working with a dataset of macroeconomic factors for a sample of countries with data ranging from 1995-2015. Im using panel data for the model and want to conduct a unit root test on each of the variables. Im using fisher type with ADF tests to conduct unit root tests for each panel individually.

WebUnit root and stationarity test statistics have nonstandard and nonnor-mal asymptotic distributions under their respective null hypotheses. To complicate matters further, the limiting distributions of the test statistics are affected by the inclusion of deterministic terms in the test regressions.
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 … See more The testing procedure for the ADF test is the same as for the Dickey–Fuller test but it is applied to the model where $${\displaystyle \alpha }$$ is a constant, See more • In R, there are various packages supplying implementations of the test.
