Is Granger causality analysis a linear operation?

Hi, Francois,

I have now completed the nonparametric test of Granger causal connection matrices under different conditions. I have a question when displaying the results: if "FDR" is chosen, there is no obvious difference between A and B, but when "uncorrcted" is selected, there will be some difference. I remember when I was doing a statistical test on source, you said that the final result must be the statistical result when choosing FDR.

Is that the same for Granger Connection Matrix? In addition, in the non-parametric test of time-frequency analysis in the Tutorial 26 about statistics, the selected item is "uncorrected".

Therefore, for the non-parametric statistical test of Granger causality analysis, whether the result of “uncorrected” selection can be regarded as the final result.
