[Help-gsl] LM non-lin fit

[Jim Cadien]

Hi,

I have been using the gsl_multifit_fdfsolver_lmsder.  My data are 
such that the errors in the independent variable are as large as 
in the dependent variable.  I see no way in the gsl routines to 
use those independent errors in the fitting.  Has anyone done 
this, and is it make a significant difference to the fit?

Thanks,

Jim
