  • ADF unit root test

    Hi, I am doing augmented dickey-fuller unit root tests for panel data, I write:

    xtunitroot fisher y, dfuller lags(1) trend

    The output lists four different statistics with corresponding p-values; but how do I obtain the actual estimation of the test statistic (i.e. 'theta' in the generic test form)? Based on theta I can estimate rho (theta = rho - 1), which is the value of interest.

    Maybe my question was not clear. What I would need is the actual estimation of the gamma coefficient:
