Surface-Fit Robust Plane

The Surface-Fit Robust Plane option in the Process menu begins TableCurve 3D's Automated Curve-Fit Processing and fits a simple plane equation by all four of the Minimization Criteria available within TableCurve 3D's non-linear fitting engine. This option also fits any installed UDFs. Note that the standard least-squares minimization is also fit using the non-linear engine to insure equal precision between the methods. This option is ideal when fitting data to a plane where outliers are likely or suspected and a robust model is desired to lessen the impact of such outliers upon the overall fit.

Fit Controls
