If you follow Hamilton's or Greene's textbook, it should not be too complicated. Based on the work of Pesaran and Shin (1998), Diebold and Yilmaz (2012) extend the spillover metric to make it invariant to ordering, by using a generalized impulse response function that does not require orthogonalization by Cholesky decomposition, and construct directional indices. RATS ignores response if you use a single IMPULSE instruction to print responses to each of the variables in turn. Heaviside(t) is zero when t < 0, 1 for t > 0 and 0.

The null hypothesis is that there is no serial correlation within each component and also between components, that is, all autocorrrelations and lagged cross correlations are zero. frame (plm package). The delta function is a normalized impulse, that is, sample number zero has a value of one, while all other samples have a value of zero. htmlIn this, the impulse is generated by using ZEROS(x,y) function, which produces an array of size X,Y with all elements as ZERO. Generalised impulse response functions (GIRFs) are calculated from the moving average representation of the VAR model, as the difference between the a conditional and unconditional forecast, where the conditioning information set is the shock to the j'th variable (koop et al (1996)).
