I found your code interesting, as I also write python curve fitting code. I saw in your code a comment about implementing RANSAC yourself, and after investigation I found the following scipy cookbook link which has a python file for this purpose. I thought it might be of interest to you.

Thanks! it looks like this project is done for now, but I'm sure I'll find a reason to use RANSAC for something else in the future.

Can I ask how you came across this repo?

I will occasionally search github for "curve fitting" and sort by "most recently updated". I found the RANSAC idea interesting, and saw that for performance reasons it was coded to use a linear solver - which means generalized linear equations only. I have both multiprocessor parallel processing and cluster computing examples for my pyeq2 and pyeq3 curve fitting libraries on github, and it would be quite easy to have nonlinear equations with RANSAC - and decent performance - if parallel or cluster computing was used.
