Nonlinear Optimization ExamplesSAS OnlineDoc : Version 8 Chapter 11 Nonlinear Optimization ExamplesOverviewThe IML procedure offers a set of Optimization subroutines for minimizing or max-imizing a continuous Nonlinear functionf=f(x)ofnparameters, wherex=(x1;:::;xn)T. The parameters can be subject to boundary constraints and linearor Nonlinear equality and inequality constraints. The following set of optimizationsubroutines is available:NLPCGC onjugate Gradient MethodNLPDDD ouble Dogleg MethodNLPNMSN elder-Mead Simplex MethodNLPNRAN ewton-Raphson MethodNLPNRRN ewton-Raphson Ridge MethodNLPQN(Dual) Quasi-Newton MethodNLPQUAQ uadratic Optimization MethodNLPTRT rust-Region MethodThe following subroutines are provided for solving Nonlinear least-squares problems:NLPLML evenberg-Marquardt Least-Squares MethodNLPHQNH ybrid Quasi-Newton Least-Squares MethodsA least-squares problem is a special form of minimization problem where the objec-tive function is defined as a sum of squares of other ()
optn = {2 2}; call nlplm(rc,xres,"F_ROSEN",x,optn); quit; The Levenberg-Marquardt least-squares method, which is the method used by the NLPLM subroutine, is a modification of the trust-region method for nonlinear least-squares problems. The F– ROSEN module represents the Rosenbrock function. Note that for least-squares problems, the m ...
