A Panel Test of Purchasing Power Parity Under the Null of Stationarity [PDF]

open access: yes, 2001
Purchasing Power Parity (PPP) is tested using a sample of real exchange rate data for twelve European countries. Acknowledging that Augmented Dickey Fuller tests have low power, we apply a Panel test that considers the null of stationarity and corrects

Memory in Memory: A Predictive Neural Network for Learning Higher-Order Non-Stationarity From Spatiotemporal Dynamics [PDF]

open access: yesComputer Vision and Pattern Recognition, 2018
Natural spatiotemporal processes can be highly non-stationary in many ways, e.g. the low-level non-stationarity such as spatial correlations or temporal dependencies of local pixel values; and the high-level variations such as the accumulation ...

On co-activation pattern analysis and non-stationarity of resting brain activity

open access: yesbioRxiv, 2021
The non-stationarity of resting-state brain activity has received increasing attention in recent years. Functional connectivity (FC) analysis with short sliding windows and coactivation pattern (CAP) analysis are two widely used methods for assessing the

A statistical test of independence in choice data with small samples

open access: yesJudgment and Decision Making, 2012
This paper develops tests of independence and stationarity in choice data collected with small samples. The method builds on the approach of Smith and Batchelder (2008).

Credibility for stationarity. [PDF]

open access: yesInsurance: Mathematics and Economics, 1996
Summary: Results for the linear credibility estimators are given for general stationary premium models. The results are derived by applying recursions and formulas of the prediction theory of stationary stochastic processes. The paper extends former results of the author [Scand. Actuarial J.

A Novel Approach for Segment-Length Selection Based on Stationarity to Perform Effective Connectivity Analysis Applied to Resting-State EEG Signals

open access: yesSensors, 2022
Connectivity among different areas within the brain is a topic that has been notably studied in the last decade. In particular, EEG-derived measures of effective connectivity examine the directionalities and the exerted influences raised from the ...

Stationarity in moment closure and quasi-stationarity of the SIS model [PDF]

open access: yesMathematical Biosciences, 2012
Previous epidemiological studies on SIS model have only considered the dynamic evolution of the mean value and the variance of the infected individuals. In this paper, through cumulant neglection, we use the dynamic equations of all the moments of infected individuals to develop a recursive method to compute the equilibria manifold of the moment ...

Is Per Capita Real GDP Stationary in G-7 Countries? New Evidence from A Fourier Panel Unit Root Test

open access: yesCumhuriyet Üniversitesi İktisadi ve İdari Bilimler Dergisi, 2021
The stability of macroeconomic variables and whether the impact of a shock on these variables is permanent or temporary is important for policy-makers and researchers.
