R help - Feb 2003 - Error analysis

Dear R experts,

I fitted data (length == m) with an external library (that's
a non-linear problem), and, I've got the final parameter vector
(length == n) and Jacobian matrix (dim == c(m, n)).  Now, I want
to analyse the standard errors of the parameters correctly.
How can I do it?
Where can I read about it else?

Thanks!

Gosh - Approximate standard errors would be discussed in almost
any advanced textbook on linear regression models.  G.A.F. Seber,
Linear Models, circa 1980, is the one I learned from.

See also G.A.F. Seber and C.J. Wild, Nonlinear Regression, 1989,
D.M. Bates and D.G. Watts, Nonlinear Regression Analysis, 1988,
or another book by Gallant (? A.R.?) which came out about the
same time.
