I don't think this is what Thomas needs. NSUR is I think nonlinear
seemingly unrelated regressions. The SUR bit means that the response is
multivariate. If he hasn't already, Thomas should look at systemfit:
systemfit: Simultaneous Equation Estimation Package
This package contains functions for fitting simultaneous systems of linear
and nonlinear equations using Ordinary Least Squares (OLS), Weighted Least
Squares (WLS), Seemingly Unrelated Regressions (SUR), Two-Stage Least
Squares (2SLS), Weighted Two-Stage Least Squares (W2SLS), Three-Stage
Least Squares (3SLS), and Weighted Three-Stage Least Squares (W3SLS).
