Testing for Structural Breaks and other forms of Non-stationarity: a Misspecification Perspective [PDF]

open access: yes
In the 1980s and 1990s the issue of non-stationarity in economic time series has been in the context of unit roots vs. mean trends in AR(p) models. More recently this perspective has been extended to include structural breaks.

Detrended Cross-Correlation Analysis: A New Method for Analyzing Two Non-stationary Time Series

open access: yes, 2007
Here we propose a method, based on detrended covariance which we call detrended cross-correlation analysis (DXA), to investigate power-law cross-correlations between different simultaneously-recorded time series in the presence of non-stationarity.

Characteristics and Mechanisms of Non‐Stationary Turbulence in a Megacity Area

open access: yesGeophysical Research Letters
Non‐stationarity challenges the applicability of turbulent similarity theory and flux estimation, especially in urban areas with highly heterogeneous underlying surfaces. Based on the observational data in Beijing, we investigated the characteristics and

A Test for Non-Stationarity of Time-Series

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1969
Summary We consider the problem of testing a given time-series for stationarity. The approach is based on evolutionary spectral analysis, and the proposed method consists essentially in testing the “homogeneity” of a set of evolutionary spectra evaluated at different instants of time. Using a logarithmic transformation, we

Trends in International Prices [PDF]

open access: yes
We exploit the panel dimension of a price levels dataset for more than one hundred product items across 140 cities in 90 countries for the period from 1990 to 2009 in order to improve our understanding of international price dispersion and the evolution ...

Wavelet Method for Locally Stationary Seasonal Long Memory Processes [PDF]

open access: yes
Long memory processes have been extensively studied over the past decades. When dealing with the financial and economic data, seasonality and time-varying long-range dependence can often be observed and thus some kind of non-stationarity can exist inside

Bayesian Reliability Analysis of Non-Stationarity in Multi-agent Systems [PDF]

open access: yesJournal of Electrical and Electronics Engineering, 2013
The Bayesian methods provide information about the meaningful parameters in a statistical analysis obtained by combining the prior and sampling distributions to form the posterior distribution of theparameters.
