Scattering parameters once a TRL calibration is performed are referred to the Zc of the micro-strip line.
Determining with measurement Zc (that is not an outcome of the calibration process) is a problem ( myabe a next question to ask about).
However from the theory we know that Zc is in general complex.

If you start with non-zero initial parameters, the iterative process won't arrive at all zero in one step. By watching the parameters and error square sum, you get an idea what goes wrong.
To know reasonable parameters, you can perform the fit with a spread sheet calculator, e.g. the Excel solver.
