Are there any Stata tests for unit root?
Panel-data unit-root tests Stata implements a variety of tests for unit roots or stationarity in panel datasets with xtunitroot . The Levin–Lin–Chu (2002), Harris–Tzavalis (1999), Breitung (2000; Breitung and Das 2005), Im–Pesaran–Shin (2003), and Fisher-type (Choi 2001) tests have as the null hypothesis that all the panels contain a unit root.
How to perform Fisher-type unit-root test for panel data?
As part of my master thesis, I’m performing several tests on panel data. One of these is a Fisher-type unit-root test, which works well with an unbalanced panel. I have performed the test, but I haven’t managed to find an explanation of how to interpret the results. The code that makes this happen is: The output for variable beta is:

How is a stochastic trend eliminated in Stata?
For example, a stochastic trend, or commonly known as a unit root, is eliminated by differencing the series. However, differencing a series that in fact contains a deterministic trend results in a unit root in the moving-average process.

Which is the null hypothesis for the unit root test?
For each case, the null hypothesis is δ = 0 , , the series have a unit root and nonstationary. In case u t are correlated, Dickey-Fuller developed a test, known as the augmented Dickey-Fuller (ADF) test. The test is conducted by “augmenting” the preceding three equations by adding the lagged values of the dependent variable Δ Y t .
