Trends and random walks in macroeconomics time series: The unit root test considerations [PDF]

open access: yesاقتصاد باثبات, 2022
In the time series econometric literature, data generation and stationary are important issues in model selection and estimation method. Difference Stationary and Trend Stationary processes are data generation procedures.

Bayesian mechanics for stationary processes [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
This paper develops a Bayesian mechanics for adaptive systems. Firstly, we model the interface between a system and its environment with a Markov blanket. This affords conditions under which states internal to the blanket encode information about external states.

Maximum Likelihood Estimation for the Fractional Vasicek Model

open access: yesEconometrics, 2020
This paper estimates the drift parameters in the fractional Vasicek model from a continuous record of observations via maximum likelihood (ML). The asymptotic theory for the ML estimates (MLE) is established in the stationary case, the explosive case ...

Ergodic properties of the solution to a fractional stochastic heat equation, with an application to diffusion parameter estimation

open access: yesModern Stochastics: Theory and Applications, 2020
The paper deals with a stochastic heat equation driven by an additive fractional Brownian space-only noise. We prove that a solution to this equation is a stationary and ergodic Gaussian process. These results enable us to construct a strongly consistent

Statistical arbitrage under the efficient market hypothesis

open access: yesStatistical Theory and Related Fields, 2020
When a financial derivative can be traded consecutively and its terminal payoffs can be adjusted into a stationary time series, there might be a statistical arbitrage opportunity even under the efficient market hypothesis.

On the Problem of Formulating Principles in Nonequilibrium Thermodynamics

open access: yesEntropy, 2010
In this work, we consider the choice of a system suitable for the formulation of principles in nonequilibrium thermodynamics. It is argued that an isolated system is a much better candidate than a system in contact with a bath. In other words, relaxation

Forecasting semi-stationary processes and statistical arbitrage

open access: yesStatistical Theory and Related Fields, 2020
If a financial derivative can be traded consecutively and its terminal payoffs can be adjusted as the sum of a bounded process and a stationary process, then we can use the moving average of the historical payoffs to forecast and the corresponding errors

Random Stationary Processes

open access: yesThe Annals of Probability, 1992
Consider a stationary process \(X=\{X_ n\}^ \infty_{n=-\infty}\) with finite state space \(A\) (the ``alphabet''). Treat \(X\) as an \(A^ \infty\)- valued function, so that its distribution constitutes a stationary probability measure \(\nu\) on \(A^ \infty\), the elements of which are called ``words''.

Abstract stationary processes [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
Concept of the multivariate stationary process is generalized to an infinite-dimensional case. Representation theorems are derived from the theory of Hilbert modules.

Matrix Algebraic Properties of the Fisher Information Matrix of Stationary Processes

open access: yesEntropy, 2014
In this survey paper, a summary of results which are to be found in a series of papers, is presented. The subject of interest is focused on matrix algebraic properties of the Fisher information matrix (FIM) of stationary processes.
