Hello, I wold like to know if is possible to fit a rational function using the Levenberg-Marquardt method (Least-Squares). In the figure below there are the equations (01, 02 and 03) I want to derive the parameters, through my experimental data. Is it possible? thank you very much, Eduardo

It is hard to understand what these function mean :) Is it three separate fitting problems, or one problem with three functions? If so, how these functions should be combined? Another question - what is the difference between small Greek coefficients (alpha's) and A/B/G/K? Do we fit with respect to some of these coefficients, considering other fixed, or what? |
