As fault detection technologies have been developed, process fault diagnosis at early abnormal stage has come to be considered a major problem. In this work, a method to analyze the root cause of faults is developed to provide proper information at the ...

The extended Granger causality analysis for Hodgkin–Huxley neuronal models
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2020How to extract directions of information flow in dynamical systems based on empirical data remains a key challenge. The Granger causality (GC) analysis has been identified as a powerful method to achieve this capability. However, the framework of the GC theory requires that the dynamics of the investigated system can be statistically linearized; i.e ...

Current Issues in Tourism, 2018
In this paper, we examine the direction of causality between tourism, economic growth and carbon emissions in a multivariate framework that incorporates the newly introduced globalization index as an additional variable.

Several studies have already assessed brain network variations in multiple sclerosis (MS) patients and healthy controls (HCs). The underlying neural system's functioning is apparently too complicated, however.

A MATLAB toolbox for Granger causal connectivity analysis
Journal of Neuroscience Methods, 2010Assessing directed functional connectivity from time series data is a key challenge in neuroscience. One approach to this problem leverages a combination of Granger causality analysis and network theory. This article describes a freely available MATLAB toolbox--'Granger causal connectivity analysis' (GCCA)--which provides a core set of methods for ...

Vegetation‐Climate Interactions on the Loess Plateau: A Nonlinear Granger Causality Analysis
Journal of Geophysical Research: Atmospheres, 2018In this study, we used a multiyear normalized difference vegetation index data set (1981–2015), and corresponding data sets for observed climatic factors, to investigate vegetation‐climate interactions on the Loess Plateau using an innovative nonlinear ...

Granger causality analysis in the neural mass model
2015 34th Chinese Control Conference (CCC), 2015The study of brain functional connectivity has become an important aspect of neuroscience. With the development of different methods to detect functional connectivity, the neural mass model based on physiology provides a basis for validating methods. As a popular method of discovering functional connectivity, Granger causality is applied to many fields

Granger causality analysis of sleep brain-heart interactions
2014 8th Conference of the European Study Group on Cardiovascular Oscillations (ESGCO), 2014We studied the networks of Granger causality (GC) between the time series of cardiac vagal autonomic activity and brain wave activities, measured respectively as the normalized high frequency (HF) component of heart rate variability and EEG power in the δ, θ, α, σ, β bands, computed in 10 healthy subjects during sleep.

Comparison Analysis: Granger Causality and New Causality and Their Applications to Motor Imagery
IEEE Transactions on Neural Networks and Learning Systems, 2016In this paper we first point out a fatal drawback that the widely used Granger causality (GC) needs to estimate the autoregressive model, which is equivalent to taking a series of backward recursive operations which are infeasible in many irreversible chemical reaction models. Thus, new causality (NC) proposed by Hu et al. (2011) is theoretically shown
