Module DODRC in CMLIB Module DODRC in CMLIBComputes 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.
