How to choose independent variables when doing 2 dimensional curve fitting
Fri, 05/19/2023 - 03:57 pm
Currently I am doing a two-dimensional data fitting (270x125). I already set up my fitting model, but I didn't know how to choose independent variables, so I am using those automatically calculated ( _calculated ). However, the resolution of the fitting results I got is not what I want. I guess this may have something to do with those independent variables in order to increase the overall fitting resolution. Any help will be appreciated and I would be happy to provide further info if needed.
Thanks in advance.
Do you mean that the fit works (you get a valid solution) but the automatically-generated model image has poor resolution? You can use the /L flag to increase the number of points used; in the dialog, go to the Output Options tab and set the resolution there.

Thanks johnweeks. I figured out this by using the /D flag, since the data I have isn't square.
