ZANDREWS: Stata module to calculate Zivot-Andrews unit root test in presence of structural break

Christopher Baum ()

Statistical Software Components from Boston College Department of Economics

Abstract: zandrews calculates the Zivot-Andrews (JBES 1992) unit root test for a timeseries allowing for one structural break in the series, which may appear in intercept, trend or both. Various criteria for detecting the structural break are supported, and the t-statistics calculated for each breakpoint may be graphed. The routine has been modified to work with a single time series from a panel.
