Webb9 apr. 2024 · Perron ( 1989) showed that structural change and unit roots are intimately related, and it is important to note that conventional unit root tests (as performed in many of the reviewed studies) are biased toward a false unit root null when the data are trend-stationary with a structural break. WebbBasic process is to fit the time series under test with an AR(1) model using heteroscedasticity- and autocorrelation-consistent residual covariance estimation in order to generate the Phillips-Perron Z-rho and Z-tau statistics (1988) which are asymptotically equivalent to the Dickey-Fuller (1979, 1981) rho/tau statistics.
