TESTING FOR TREND STATIONARITY VERSUS DIFFERENCE STATIONARITY

Journal of Time Series Analysis, 1995
Abstract. Testing the null hypothesis that a process is difference stationary has received considerable attention in the past decade. Recently, there has been some interest in testing the null hypothesis that a process is a sum of a linear trend and a stationary invertible noise sequence.

Stationarity of the human electroencephalogram

Medical and Biological Engineering and Computing, 1977
The time and frequency domain characteristics of the human electroencephalogram continue to be parameters of significant interest to both research workers and clinicians alike. In nearly every analysis of the e.e.g., the question of stationarity is raised.

STATIONARITY OF DELAYED SUBORDINATORS

Stochastic Models, 2001
It is shown that, analogous to partial-sum processes in renewal theory, nondecreasing Levy processes (subordinators) can be delayed such as to show a certain stationarity.

Stationarity in Neuromonitoring Data

2012
Signals reflecting the metabolic and circulatory status of an injured central nervous system are normally corrupted systematically. The patient is part of a therapeutic control-loop and the signals acquired are rather determined by the quality of control (stationarity of signals) than by the underlying pathological process.To verify the control-loop ...

STATIONARITY TESTING WITH COVARIATES

Econometric Theory, 2004
Summary: Two new stationarity tests are proposed. Both tests can be viewed as generalizations of existing stationarity tests and dominate these in terms of local asymptotic power. Improvements are achieved by accommodating stationary covariates. A Monte Carlo investigation of the small sample properties of the tests is conducted, and an empirical ...
