Description length guided nonlinear unified Granger causality analysis [PDF]

open access: yesHarvard Data Science Review, 2023
Abstract Most Granger causality analysis (GCA) methods still remain a two-stage scheme guided by different mathematical theories; both can actually be viewed as the same generalized model selection issues. Adhering to Occam’s razor, we present a unified GCA (uGCA) based on the minimum description length principle.

New Insights into Signed Path Coefficient Granger Causality Analysis [PDF]

open access: yesFrontiers in Neuroinformatics, 2016
Granger causality analysis, as a time series analysis technique derived from econometrics, has been applied in an ever-increasing number of publications in the field of neuroscience, including fMRI, EEG/MEG, and fNIRS. The present study mainly focuses on

Granger Causality Analysis of Chignolin Folding. [PDF]

open access: yesJ Chem Theory Comput, 2022
Constantly advancing computer simulations of biomolecules provide huge amounts of data that are difficult to interpret. In particular, obtaining insights into functional aspects of macromolecular dynamics, often related to cascades of transient events, calls for methodologies that depart from the well-grounded framework of equilibrium statistical ...

Bibliometric Analysis of Granger Causality Studies

open access: yesEntropy, 2023
Granger causality provides a framework that uses predictability to identify causation between time series variables. This is important to policymakers for effective policy management and recommendations.

Sparse Granger Causality Analysis Model Based on Sensors Correlation for Emotion Recognition Classification in Electroencephalography [PDF]

open access: yesFrontiers in Computational Neuroscience, 2021
In recent years, affective computing based on electroencephalogram (EEG) data has attracted increased attention. As a classic EEG feature extraction model, Granger causality analysis has been widely used in emotion classification models, which construct ...

Description Length Guided Unified Granger Causality Analysis [PDF]

open access: yesIEEE Access, 2021
In this article, we propose a description length guided unified Granger causality analysis (uGCA) framework for sequential medical imaging. While existing efforts of GCA focused on causal relation design and statistical methods for their improvement, our

Granger causality analysis in neuroscience and neuroimaging. [PDF]

open access: yesJ Neurosci, 2015
### Introduction A key challenge in neuroscience and, in particular, neuroimaging, is to move beyond identification of regional activations toward the characterization of functional circuits underpinning perception, cognition, behavior, and consciousness.

Multivariate Timing and Granger Causality Analysis of Spontaneous Facial Mimicry in Response to Android Dynamic Facial Expressions [PDF]

open access: yesSensors
Although evidence exists for android-induced spontaneous facial mimicry, the timing and temporal precedence (Granger causality) of this effect remain uncertain.

Robust unified Granger causality analysis: a normalized maximum likelihood form [PDF]

open access: yesBrain Informatics, 2021
Unified Granger causality analysis (uGCA) alters conventional two-stage Granger causality analysis into a unified code-length guided framework. We have presented several forms of uGCA methods to investigate causal connectivities, and different forms of ...
