Greetings!

I try to fit my XYZ data with Plane using Nonlinear Fit.
Recently I noticed that if I choose Levenberg Marquardt iteration algorithm, the the Residual Plot option is missing in the menu:


Was this made by purpose or a bug?

Thank you.

Hi,

I have added your suggestion to JIRA (ORG-21616) to implement this in the future version.
Thank you for the suggestion.

Thanks,
Amanda

If Z residual plot, what’s the XY you want? Source X, source Y vs residual Z?

Yes, sure.
Does is make sense?

Hi,

In LM, there is only 1 residual data (Z), and we use contour plot: source X, source Y, residual Z.
In ODR, there is 3 residual data, X/Y/Z has its own one. We do not know what kind of plot type can be used to represent it yet.
That’s why we don’t output residual for ODR.

Thanks,

That would be great to get Z residual in case of ODR.

Orthogonal Distance Regression cannot support residual plots.

What is the reason for this?
Can you add the residuals calculation and plotting for ODR option?
