The solution of the SURE model with singular variance-covariance matrix results in redundancies and possibly inconsistencies among the observations of the model. A numerical procedure is proposed and investigated that generates a consistent model from an inconsistent one. The use of SVD has been...

The Vector Autoregressive (VAR) model with zero coefficient restrictions can be formulated as a Seemingly Unrelated Regression Equation (SURE) model. Both the response vectors and the coefficient matrix of the regression equations comprise columns from a Toeplitz matrix. Efficient numerical and...

This paper investigates parallel solution methods to simulate large-scale macroeconometric models with forward-looking variables. The method chosen is the Newton-Krylov algorithm, and we concentrate on a parallel solution to the sparse linear system arising in the Newton algorithm. We...
