Hello

I perform non-linear fitting in origin and get very suprising results.
the result is 0.12 but the error is 7638.21

why is that?

thank you!

Hi,

You can indeed get very large errors on parameters if for example the model is not a good match to your data, if the function has too many parameters that are interdependent etc. Hard to tell what is going on without seeing the data and the function. If you need further help, please contact tech support.
