THE ROLE OF RELIGIOUS TOURISM IN SUSTAINABLE DEVELOPMENT IN SAUDI ARABIA: EVIDENCE FROM QUANTILE NON-CAUSALITY TEST [PDF]

open access: yesGeo Journal of Tourism and Geosites, 2019
This paper empirically examines the role of religious tourism in sustainable development to the projection of Saudi Arabia 2030. This study observes the causal relationship between hajj pilgrims and economic growth in the KSA by conducting a quantile ...

Correntropy based Granger causality [PDF]

open access: yes2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
We propose a novel nonlinear extension to Granger causality. It is derived from a nonlinear mapping of a stochastic process using the recently introduced generalized correlation measure called correntropy. The method is demonstrated by detecting the direction of coupling in a chaotic system where the original Granger causality failed.

A Pitfall in Using the Characterization of Granger Non-Causality in Vector Autoregressive Models

open access: yesEconometrics, 2015
It is well known that in a vector autoregressive (VAR) model Granger non-causality is characterized by a set of restrictions on the VAR coefficients. This characterization has been derived under the assumption of non-singularity of the covariance matrix ...

Attention-dependent modulation of cortical taste circuits revealed by granger causality with signal-dependent noise [PDF]

open access: yes, 2013
We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

BOLD Granger causality reflects vascular anatomy. [PDF]

open access: yesPLoS ONE, 2013
A number of studies have tried to exploit subtle phase differences in BOLD time series to resolve the order of sequential activation of brain regions, or more generally the ability of signal in one region to predict subsequent signal in another region ...

Designing Bivariate Auto-Regressive Timeseries with Controlled Granger Causality

open access: yesEntropy, 2021
In this manuscript, we analyze a bivariate vector auto-regressive (VAR) model in order to draw the design principle of a timeseries with a controlled statistical inter-relationship.

Meta-Granger Causality Testing [PDF]

open access: yesSSRN Electronic Journal, 2015
Understanding the (causal) mechanisms at work is important for formulating evidence-based policy. But evidence from observational studies is often inconclusive with many studies finding conflicting results. In small to moderately sized samples, the outcome of Granger causality testing heavily depends on the lag length chosen for the underlying vector ...

Causality Between Brent and West Texas Intermediate: The Effects of COVID-19 Pandemic and Russia–Ukraine War

open access: yesCommodities
The article analyzes the Granger-based causal relationship between two major crude oil markets, namely Brent and West Texas Intermediate (WTI), by using the standard vector autoregression (VAR) framework.

On the Validity of Granger Causality for Ecological Count Time Series

open access: yesEconometrics
Knowledge of causal relationships is fundamental for understanding the dynamic mechanisms of ecological systems. To detect such relationships from multivariate time series, Granger causality, an idea first developed in econometrics, has been formulated ...
