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.

Stationarization via surrogates [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2009
The surrogate data method, classically used for non-linearity tests, amounts to the use of some constrained noise providing a reference for statistical testing. It is revisited here as a method for stationarization and this feature is put forward in the context of non-stationarity testing.

Prediction of fatal accidents in Indian factories based on ARIMA

open access: yesProduction Engineering Archives, 2018
The inherent benefits of an accident prevention program are generally known only after an accident has occurred. The purpose of implementation of the program is to minimize the number of accidents and cost of damages. Allocation of resources to implement

Is There A Stable Long-run Relationship Between Unemployment And Productivity?

open access: yesComparative Economic Research, 2015
This paper assesses whether productivity and unemployment have a stable long-run relationship. We explore a panel of 19 OECD countries between 1970 and 2012 and rely on recently developed time series econometric methods.

The Taylor Property in Bilinear Models

open access: yesRevstat Statistical Journal, 2015
The aim of this paper is to discuss the presence of the Taylor property in the class of simple bilinear models. Considering strictly and weakly stationary models, we deduce autocorrelations of the process and of its square and analyze the presence of ...

Monitoring Stationarity and Cointegration [PDF]

open access: yesSSRN Electronic Journal, 2015
We propose a monitoring procedure to detect a structural change from stationary to integrated behavior. When the procedure is applied to the residuals of a relationship between integrated series it thus monitors a structural change from a cointegrating relationship to a spurious relationship. The cointegration monitoring procedure is based on residuals

Noise Cancellation with Static Mixtures of a Nonstationary Signal and Stationary Noise

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
We address the problem of cancelling a stationary noise component from its static mixtures with a nonstationary signal of interest. Two different approaches, both based on second-order statistics, are considered. The first is the blind source separation (
