WebThe main goal is to apply VAR (Vector Autoregression) model to infer Granger Causality between groups of time series extracted from preprocessed EPI (fMRI) data by means of Canonical Correlation Analysis. The measure of Granger causality will be used to generate functional maps of brain connectivity. (Supported by FAPESP) WebGranger causality is a fundamental technique for causal inference in time series data, commonly used in the social and biological sciences. Typical operationalizations of Granger causality make a strong assumption that every time point of the effect time series is influenced by a combination of other time series with a fixed time delay.

Additional functions afterwards can estimate, for example, the average_treatment_effect (). See help (package='grf') for more options.
Web2vargranger— Perform pairwise Granger causality tests after var or svar Because it may be interesting to investigate these types of hypotheses by using the VAR that underlies an SVAR, vargranger can also produce these tests by using the e() results from an svar. When vargranger uses svar e() results, the hypotheses concern the underlying var estimates.
