HADRILM: Stata module to perform Hadri panel unit root test
Abstracthadrilm performs a test for stationarity in heterogeneous panel data (Hadri, 2000). This Lagrange Multiplier (LM) test has a null of stationarity, and its test statistic is distributed as standard normal under the null. The series may be stationary around a deterministic level, specific to the unit (i.e. a fixed effect) or around a unit-specific deterministic trend. The error process may be assumed to be homoskedastic across the panel, or heteroskedastic across units. The residual-based test is based on the squared partial sum process of residuals from a demeaning (detrending) model of level (trend) stationarity. This is version 1.0.3 of the software. Users of Stata 11+ should use the official xtunitroot hadri command.
