Testing for unit roots in time series with level shifts
Tests for unit roots in univariate time series with level shifts are proposed and investigated The level shift is assumed to occur at a known time It may be a simple one time shift which can be captured by a dummy variable or it may have a more general form which can be modeled by some general nonlinear transition function There may also be more than one shift point and there may be other deter...
متن کاملTesting for seasonal unit roots in monthly panels of time series
We consider the problem of testing for seasonal unit roots in monthly panel data. To this aim, we generalize the quarterly CHEGY test to the monthly case. This parametric test is contrasted with a new nonparametric test, which is the panel counterpart to the univariate RURS test that relies on counting extrema in time series. All methods are applied to an empirical data set on tourism in Austri...
متن کاملTesting for Seasonal Unit Roots
This paper examines, both theoretically and through Monte Carlo analysis, the implications of applying the HEGY seasonal root tests to a process that is periodically integrated. As an important special case, the random walk process is also considered. In the context of the HEGY regression, the asymptotic distribution of the zero frequency test statistic is dependent on the coefficients of the p...

Testing for unit roots in autoregressions with multiple level shifts ∗
The asymptotic distributions of Augmented-Dickey-Fuller (ADF) unit root tests for autoregressive processes with a unit or near-unit root are discussed in the presence of multiple stochastic level shifts of large size occurring independently in time. The distributions depend on a Brownian motion and a Poisson-type jump process. Due to the latter, tests based on standard critical values experienc...
