[Q] How to compare if two fits are significantly different from each other



Hi,

I am looking for a means to determine how two fits are significantly
different from each other.
I have data and made two fits to my data using different fitting
functions. The question I have is how to determine whether one fit is
significantly better than the other one.

I thought about comparing their Chi sqaure values. This way, I could
say that which one is a better fit, but I could not say how much better
(significance) it is compare to the other one.

Can anyone help me with this problem?

Thanks in advance.
