Granger-causality metrics have become increasingly popular tools to identify directed interactions between brain areas. However, it is known that additive noise can strongly affect Granger-causality metrics, which can lead to spurious conclusions about neuronal interactions. To solve this problem, previous studies have proposed the detection of Granger-causal directionality, i.e. the dominant G...

Granger causality analyses aim to reveal the direction of influence between brain areas by analyzing temporal precedence: if a signal change in area A consistently precedes a signal change in area B, then A Granger-causes B. fMRI-based Granger causality inferences are mediated by the hemodynamic response function which can vary across brain regions. This variability might induce a bias in Grang...

This article investigates the causality structure of financial time series. We concentrate on three main approaches to measuring causality: linear Granger causality, kernel generalisations of Granger causality (based on ridge regression and the Hilbert–Schmidt norm of the cross-covariance operator) and transfer entropy, examining each method and comparing their theoretical properties, with spec...

The paper examines the causal nexus between financial development and economic growth in India in a multivariate VAR model. The empirical analysis is based on cointegration and causality test. The cointegration test finds the presence of long run equilibrium relationship between financial development and economic growth. The Granger causality test finds the existence of bidirectional causality ...

abstract in this paper, we examine relationship between financial intermediary development variables and values added of agricultural sector in iran during 1352 to 1385. the five indices derived from the banking system as a financial intermediary development indicators, that define in related to the agricultural sector, and with the introduction of statistic methods of factor analysis and its a...

t his paper investigates the existence of possible spillover effects among four main asset markets namely foreign exchange, stock, gold, and housing markets in iran from 2002:03 to 2015:06. for this purpose, we have exploited sigma-point kalman filter (spkf) to extract the bubble component of assets prices in the aforementioned markets. then, in order to analyze the price bubbles spillover amon...

To examine the long-term causality between Cardiorespiratory Electromyography Galvanic signals for 17 drivers taken from Stress Recognition in Automobile Drivers database. Methods: Two statistical methods, co-integration to reveal an eventual existence of a long-term relationship between ECG (Electrocardiograph), EMG (electromyography), GSR (galvanic skin resistance), heart rate (HR) and respir...

We address a consistency problem in the commonly used nonparametric test for Granger causality developed by Hiemstra and Jones (1994). We show that the relationship tested is not implied by the null hypothesis of Granger non-causality. Monte Carlo simulations using processes satisfying the null hypothesis show that, for a given nominal size, the actual rejection rate may tend to one as the samp...
