SODR

 
Computes the weighted orthogonal distance regression or ordinary linear or
nonlinear least squares solution. Derivatives are either supplied by the user or
numerically approximated. Control values are preset, and a two-part report of
the results is automatically generated.
 
Classes  :  K1a1a3 . Unconstrained linear least squares approximation on
                   univariate data (curve fitting)
            K1b1a1 . Unconstrained nonlinear least squares approximation by
                   smooth functions, user provides no derivatives
            K1b1a2 . Unconstrained nonlinear least squares approximation by
                   smooth functions, user provides first derivatives
            L8a4 .   Simple linear errors in variables regression
            L8c5 .   Measurement error models
            L8e5 .   Nonlinear measurement error models
