Thank you Yuki.

The first link gives a general theory for non-linear curve fitting. The second link has minimal details of RationalTaylor fit.

Can you please share documentation of the detailed theory of RationalTaylor.

Regards,
Aher

Hi Aher,

I have shown you all we have so far.

We handle all the cases of non-linear fit like the page above, and we don’t have a specified page for the theory of RationalTaylor like you mentioned.

Regards, Yuki
