As a final note - the model you're specifying is probably not going to … WebIf x is an M × N matrix, then xcov(x) returns a (2M – 1) × N 2 matrix with the autocovariances and cross-covariances of the columns of x. If you specify a maximum lag maxlag, then the output c has size (2 × maxlag + 1) × N 2. For example, if S has three columns, S = (x 1 x 2 x 3), then the result of C = xcov(S) is organized as

Web9 aug. 2024 · As stated here, in order to run a Granger Causality test, the time series' you are using must be stationary. A common way to achieve this is to transform both series by taking the first difference of each: x = np.diff (x) [1:] y = np.diff (y) [1:] Here is the comparison of Granger Causality results at lag 1 and lag 25 for the similar dataset I ...
