Quality research begins with reliable and comprehensive unit root testing.
Inadequate unit root testing jeopardizes research results.
Most time series and panel data estimation techniques depend on establishing whether data is stationary or results can be unreliable.
Standard unit root tests can’t capture the complexities of real-world data.
Failing to account for characteristics such as structural breaks or panel data relationships means losing important information.
