Hello Heinz,
You can have a look at pages 45-49 of my slides on least Squares :
http://www.utc.fr/~mottelet/mt94/leastSquares.pdf
Page 48 you have an example where the Covariance matrix is
approximated for a fitting problem with an ode defined page 42.

Quoting Heinz Nabielek :
Scilab
Scilab friends: the power of Scilab is amazing and I have used it recently for
non-linear least-squares fitting, below example from Scilab help function for
"datafit". On occasions, I have also used "leastsq".
Question: how do I derive the 1sigma standard error in the three parameters
p(1), p(2
