WebAug 22, 2024 · We recently proposed a causal network of structural covariance (CaSCN) approach, which applies granger causality analysis (GCA) to sequenced cross-sectional morphometry according to disease progression information (Zhang et al., 2024 ). WebJan 4, 2024 · To address the aforementioned problems, in this letter, we propose a new method called GCA based on the quantized MEE (QMEE) criterion (GCA-QMEE), in which the QMEE criterion is applied to identify the LRM coefficients and the quantized error entropy is used to calculate the causality indexes.

WebApr 5, 2024 · Predictive (Granger) causality and feedback is an important aspect of applied time-series and longitudinal panel-data analysis. Granger (1969) developed a statistical concept of causality between two or more time-series variables, according to which a variable x “Granger-causes” a variable y if the variable y can be better predicted using …
WebApr 13, 2024 · In this paper, we propose a new approach to analyze financial contagion using a causality-based complex network and value-at-risk (VaR). We innovatively combine the use of VaR and an expected shortfall (ES)-based causality network with impulse response analysis to discover features of financial contagion.
