چکیده
We thank Drs Schouten and Campfens for their interest in our paper. We are more optimistic about the practical capabilities of directed coherence than the position they adopt in their letter, but we would also emphasise the need for caution in using these methods. At the basis of directed coherence (Granger causality) methods is an autoregressive model of the signals of interest. For the bivariate case, this can be expressed as:

متن کاملTHE ANALOGUE OF WEIGHTED GROUP ALGEBRA FOR SEMITOPOLOGICAL SEMIGROUPS
In [1,2,3], A. C. Baker and J.W. Baker studied the subspace Ma(S) of the convolution measure algebra M, (S) of a locally compact semigroup. H. Dzinotyiweyi in [5,7] considers an analogous measure space on a large class of C-distinguished topological semigroups containing all completely regular topological semigroups. In this paper, we extend the definitions to study the weighted semigroup ...
