Multivariate ARMA Model
...estimate an ARMA(1,1)-model. For multivariate processes there are the functions "estVARXar" and "estVARXls" from package "DSE". But how can I estimate an VARMA(1,1)-model, or even better determine the orders and estimate the parameters? Much thanks in advance, Hagen Schmoeller -- Dipl.-Ing. Hagen K.

DSE: covariance of white noise
..., 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?
