I have a set of datapoints with x (position) errors as well as y (measurement) errors. Is there a way in Mathematica to fit a nonlinear function through this points, with weighting both, the x and y errors?

  • Please post your datapoints. Also this might help you https://www.youtube.com/watch?v=KolZZm8If9Q – Conor Jan 30 '16 at 13:22
  • Unfortunately the video didnt help, it just shows normal nonlinear fitting, I need it with the weighting of x and y errors though. – Luca Thiede Jan 30 '16 at 14:02

    This has been asked a number of times already on this site. For example: (13054), (33273), (27101) (there are surely others). Basically, the linear case can be done somewhat straightforwardly, but nonlinear is more difficult mathematically. I suggest you proceed with it as a minimization problem. It has been demonstrated in (24788). – Oleksandr R. Jan 30 '16 at 14:36
