[R] DSE: covariance of white noise

[Hagen Schmöller]

Hi R-Community,

I estimated a VARMA model with bft in dse1 without input: A(L)yt = B(L)et

I got the auto-regressive polynomial array A and the moving-average
polynomial array B, but how can I access the covariances of the white noise
et (disturbance vector), e.g. for simulation?

Much thanks in advance,
