Optimization method used.

Syntax
C#
Visual Basic
public TOptMethod OptMethod;
Remarks

Defines which optimization method will be used to find regression coefficients estimates. Several different optimization algorithms are supported (see Dew Math Optimization assembly help for more on this topic):

  • optSimplex : Nelder-Mead optimization method.
  • optMarquardt : Marquardt optimization method.
  • optBFGS : Quasi-Newton optimization method (Broyden-Fletcher-Goldfarb-Shanno Hessian update).
  • optDFP: Quasi-Newton optimization method (Davidson-Fletcher-Power Hessian update).
  • optConjGradFR: Conjugate Gradient optimization method (Fletcher-Reeves).
  • optConjGradPR : Conjugate Gradient optimization method (Polak-Ribiere).
