Granger causality
Granger causality is a statistical concept of causality that is based on prediction. According to Granger causality, if a signal X1 "Granger-causes" (or "G-causes") a signal X2, then past values of X1 should contain information that helps predict X2 above and beyond the information contained in past values of X2 alone. Its mathematical formulation is based on linear regression modeling of stoch...
متن کامل[Profesionalismo en médicos de un hospital de segundo nivel].
BACKGROUND It takes many years to acquire abilities and technical skills necessary to do a good work as a doctor and even more years, for being "good professionals". Much of this training is based on old teaching schemes, but medicine has changed. So far no studies in our medium addressing the problem are known. The aim of this paper was to determine the level of professionalism in physicians t...
متن کاملThe MVGC multivariate Granger causality toolbox: a new approach to Granger-causal inference.
BACKGROUND Wiener-Granger causality ("G-causality") is a statistical notion of causality applicable to time series data, whereby cause precedes, and helps predict, effect. It is defined in both time and frequency domains, and allows for the conditioning out of common causal influences. Originally developed in the context of econometric theory, it has since achieved broad application in the neur...
متن کاملWiener-Granger Causality: A well established methodology
For decades, the main ways to study the effect of one part of the nervous system upon another have been either to stimulate or lesion the first part and investigate the outcome in the second. This article describes a fundamentally different approach to identifying causal connectivity in neuroscience: a focus on the predictability of ongoing activity in one part from that in another. This approa...
متن کاملGranger causality revisited
This technical paper offers a critical re-evaluation of (spectral) Granger causality measures in the analysis of biological timeseries. Using realistic (neural mass) models of coupled neuronal dynamics, we evaluate the robustness of parametric and nonparametric Granger causality. Starting from a broad class of generative (state-space) models of neuronal dynamics, we show how their Volterra kern...
