DODRC

 
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 supplied by the user, and a
three-part report of the results is optionally 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
