If P-value is less than 5% (or 0.05), then we can reject the Null hypothesis (H0), and can conclude that Xt granger causes Yt. So where ever your P-value is less than 0.05, you can consider those features. Share.

Improved tests for Granger noncausality in panel data

WebAbstract. Granger causality or G-causality is a measurable concept of causality or directed influence for time series data, defined using predictability and temporal precedence. A variable y G-causes another variable x if the prediction of x ’s values improves when we use past values of y, given that all other relevant information z is taken ... In other words, if you find Granger causality in your data there isn’t a causal link in the true sense of the word (for example, sales of Easter baskets Granger-cause Easter!). Note : When econometricians say “cause,” what they mean is “Granger-cause,” although a more appropriate word might be “precedence” … See more Granger causality is a way to investigate causality between two variables in a time series. The method is a probabilistic account of causality; it uses empirical data sets to find patterns … See more Granger causality is a “bottom up” procedure, where the assumption is that the data-generating processes in any time series are independent variables; then the data sets are … See more The procedure can get complex because of the large number of options, including choosing from a set of equations for the f-value calculations. … See more The null hypothesis for the test is that lagged x-values do not explain the variation in y. In other words, it assumes that x(t) doesn’t Granger-cause y(t).
