ODRPACK95: A Weighted Orthogonal Distance Regression Code with Bound Constraints
2004) ODRPACK95: A Weighted Orthogonal Distance Regression Code with Bound Constraints. Technical Report TR-04-31, Computer Science, Virginia Tech. (
ODRPACK (TOMS Algorithm 676) has provided a complete package for weighted orthogonal distance regression for many years. The code is complete with user selectable reporting facilities, numerical and analytic derivatives, derivative checking, and many more features. The foundation for the algorithm is a stable and efficient trust region Levenberg-Marquardt minimizer that exploits the structure of the orthogonal distance regression problem. ODRPACK95 is a modification of the original ODRPACK code that adds support for bound constraints, uses the newer Fortran 95 language, and simplifies the interface to the user called subroutine.
